Back in late 1999, when Power Mac G4 computers first arrived on the scene, most came with a DVD-RAM drive. It's not a mystery why Apple initially put its faith in this format. They had the advantages of floppy disks but without their downsides. Specifically, DVD-RAM discs offered much greater capacity and reliability than floppies; yet (as with floppies) you could copy files to or delete files from a disc on an file-by-file basis. You could even modify and re-save a document already contained on a disc. Put simply, the discs could be used repeatedly, modifying their contents as desired, with no hassles. In contrast, today's DVD±RW discs have to be completely erased before you can re-use them and DVD±R discs can only be used once! [Technical note: Yes, I am glossing over the little-used and awkward multi-session burning here.]
Despite all of these advantages, Apple's experiment with this format ended about a year after it began. There is no formal obituary that details the causes of this early death, but I am reasonably certain what happened. First, and foremost, a different DVD format was becoming increasingly popular as a medium for movies. As there were no drives that could read from and write to both the DVD-RAM and DVD±R formats, Apple had to choose one or the other. Apple was just recovering from its miscalculation of the demand for CD-burners (having initially gone with DVD-ROM drives in its iMacs rather than CD-RW drives). It was not going to make the same mistake again. They had to go with the format that was being used with the rapidly growing number of DVD players out there. Eventually, the SuperDrive arrived, with its ability to both read from and write to the common CD and DVD formats (but not DVD-RAM). If there was any doubt as to what Apple would use, it ended with the SuperDrive.
The potential success of DVD-RAM was also hurt because the discs need to be placed in a bulky cartridge before you could use them. Plus, the other CD and DVD formats were rapidly outpacing DVD-RAM in terms of reading and burning speeds.
And so, DVD-RAM drives joined OpenDoc and the Newton and all of the other products that are in Apple's abandoned technology heap. And eventually DVD-RAM drives faded out of existence altogether. Or so I thoughtuntil about a year ago when I began to shop for something to replace my VCR. I wanted something mainly as a means of recording TV shows for my now-frequent time-shifting. I looked at TiVo, of course, but decided against it (I have since relented, having purchased one last month). My initial reluctance was for two reasons. First, I did not want to commit to paying a monthly fee on top of what I was already paying for cable. Second, I wanted the ability to record a show on one TV and play it back on another, without any fuss.
I looked at plain-vanilla DVD recorders, but did not like them either. As I intended to primarily record programs that I did not care to save after viewing, I was not happy either with the limitations of DVD±RW discs or (even worse) having to discard DVD±R discs after one use.
And that's when I discovered Panasonic DVD recorders. They included, of all things, a DVD drive with DVD-RAM support. But these were not the same DVD-RAM drives used by Apple years before. The discs for these new drives have greater capacity (matching the 4.7GB of single-layer DVD-ROM discs), the drives support all the other CD (for reading only) and DVD (for writing and reading) formats, and they don't require using a cartridge. In essence, I could get my cake and eat it too. With one drive, I could have the advantages of DVD-RAM without sacrificing compatibility with the other more common formats. This meant, for example, that I could record two weeks or more of The Daily Show on one DVD-RAM disc. After watching one show, I could simply select to erase it, freeing up its space for recording a new show while leaving all other recorded shows untouched. The erasure is simple and quick, taking only a few seconds to do. I could keep using this same DVD-RAM disc over and over, saving money as well as hassle.
As a bonus, with DVD-RAM discs, the drive offers chasing playback, much like a TiVo device. This means that, for example, if I get home 30 minutes into the recording of a 60 minute show, I can select to watch the show from the beginning, with the ability to skip commercials(!), while the drive continues to record the latter half of the show.
One downside, of course, is that these DVD-RAM discs cannot be played on most other brands of DVD drives. But, after I discovered that I could get a Panasonic DVD player (not a recorder) with DVD-RAM support for about $70, I wound up getting two Panasonic drives (one recorder and one player)all for under $250. The recorder was missing several of the convenience features of TiVo, but I had no monthly fee to pay. Overall, I have been quite happy with these drives.
All of this leads me full circle back to the Mac. With one of these new-generation multi-format drives attached to my Mac, I could use DVD-RAM discs as removable mini-hard drives for storing data. Not as fast, obviously, but adequate for many tasks. Plus, I would still be able to use the drive as a player for movie DVDs or for burning standard DVDs when desired.
I am not counting on Apple adding DVD-RAM drives as a build-to-order option any time soon. But what about purchasing an external multi-format DVD-RAM drive? Yes, they do exist. But you would be hard-pressed to find them. Searches for these drives on Amazon came up empty or nearly-so. I did find a Sony model at PC Mall. A few sites also carry drives made by LG and Panasonic. Availability is apparently greater in Europe and Asia. For example, Amazon's UK site stocks several DVD-RAM drive models.
The specs indicate that these drives should work fine with a Mac. There is a potential minor snag with the type of format preferred for these discs (UDF instead of Apple's HFS Plus), but it is not a deal-breaker (see Wikipedia for more background on this).
I know. DVD-RAM is not likely to ever make a significant comeback. There is just too much momentum in the other direction for it to overcome. To be honest, even after writing all of this, I have not yet purchased one of these external drives and I am not sure I ever will. But I am thinking about it. Regardless, I do wonder what might have been, if history had started down a slightly different path back in 1999.

I used to use DVD-RAM (still have an external drive hooked to my PowerMac G5). I also have a couple of Panasonic recorders - one with a hard drive and DVD-RAM, and one with just the DVD-RAM drive. I found the disks to be unreliable after 20 or 30 cycles of record/erase, which is why I upgraded from the DVD-RAM only drive to the one with the hard drive in it. I can always spool off from the hard drive to DVD-RAM (or DVD-R, as the drive supports both).
I had one of the early drives that had only 2.3 gig capacity, but I loved it despite the bulky cartridge. The reasons being exactly what you mentioned about it working just like a hard drive (except slower). Even after DVD-R and DVR+R came out, I knew that DVD-RAM was the only good format for computer use.
Thu May 25, 2006 9:54 am Subject: Had the DVD-RAM Option in my G4
My biggest problem with the DVD-RAM drive was finding the right media - there were a bunch of different formats. At the time I bought my G4, neither the instructions nor the Kbase never specified which type of media was needed. It took several tries (expensive ones at that) to find the right format.
Ultimately, I found it too slow, too inconvenient and just too small to use as a back-up disc, since I was already ripping my music collection into iTunes. I ended up buying an external DVD RW drive, and still use it with the G5 - to make back ups for off-site storage.
Per MB DVD-RAM cost a lot more than DVD-R, or DVD+R. Hard drives cost less, and thanks to Elgato's EyeTV 200 and Toast , I now have converted my entire 150 tape VHS collection to DVD in 6 months. It fits 8 hours of video snugly on double sided DVD. In addition, the software ties directly into the Cable TV guide for my area, so I can select what I want to record to DVD and do it pretty smoothly. The EyeTV has both Composite for Cable/VHS connection and S-Video for connection to DVD players. True I don't get the full HD resolution, but on HD-TVs which have pixel interpolation you don't notice the difference.
My G4 minitower (originally 500MHz, upgraded to 1GHz) came with a DVD-RAM drive. I ended up replacing it with a SuperDrive. The problem with DVD-RAM is it was very slow, not well supported in OS X (this was before 10.2, I don't know if it changed), and the media was hard to find & expensive.
At the time of floppies for most people and zip drives for the "adopters" the DVD-RAM was something of a marvel. I loved the thing... although it was the move to OS X with an attempt at putting the drive into an external enclosure that ended things for me. The enclosure claimed it would support it... but calls to the manufacturer proved otherwise. OS X may have supported it, but due to enclosure issues we'll never know. And the DVD-RAM faded into history

Thu May 25, 2006 8:45 pm Subject: DVD recorders with HDs
I'd agree with several commentors who prefer DVD recorders with HDs. You avoid the monthly fee to TiVo, can save what you want and delete the rest, all with much greater reliability and storage capacity than DVD-RAM. (One of my DVD recorders came with a DVD-RAM disk, as well as the HD.) The DVD-RAM holds 4.7 GB; my DVD recorder's HD is 160 GB, a bit over 70 hours at normal quality--more at lower quality (essentially the difference between DVD and VCD).
For what Ted paid for the DVD player and recorder, he could have bought El Gato's EyeTV or another of the good video capture devices that use El Gato's software.

It seems sort of silly that after all these years, we still don't have a REAL successor to the floppy.
Sue we do. They're called "flash drives." No, you don't want to use them for "archiving," but floppies were never very good for that, either, not to mention the @#$(*& Zip disks.
Floppies are MUCH less reliable, a lot slower, hold less, and often cost more than CD-R discs. With multisesson recording, you can add data to CD-Rs until they're full. At as little as $0.20 each, CD-Rs are the way to go.
Here's a tip: in System Preferences->CDs and DVDs, choose to open the Finder when you insert a blank CD. That will put a disk image on your desktop when you insert the CD. You can add files and folders, delete them, modify them, etc. Then, when you want to burn the CD, just drag the image's icon to the trash. (You can also create a disk image using Disk Utility. That's the way to go if you want multisesson burning.)
I still use a G5 500MHz DP. I've got DVD-RAM in 5.2 and 9.4 GB sizes. They work well for smaller backups. I used them a couple of times for conveniently storing software updates I would need after installing new hard drives. The disks may not be speedy but play back iMovies just fine. With over 100,000 rewrites possible on the disks I will clearly get my money's worth if I keep my G5 going.
is a format supported by the new HP 840i drive - it does + and - DVD R and RW formats, and RAM. I tried the internal drive in my firewire case, and it didn't work reliably (HP has a note in their knowledgebase to the effect that internal drives are expected to be used internally, and they don't guarantee compatibility with external case solutions). Since I was using a Pioneer 110 in the external case, I just stuck the HP drive into my PC, replacing its old NEC 4x DVD +-RW drive. I have read of people using the HP drive with the Mac, I assume internally, but I didn't try that.
with a Pioneer, the only brand I'll touch, was the original Superdrive, and supplied by Apple for years, DVR-110D. Re-Flashed, updated the firmware, with the 110 (no D) version and got:
PIONEER DVD-RW DVR-110:
Firmware Revision: 1.39
Interconnect: ATAPI
Burn Support: <strong>Yes (Apple Shipped/Supported)</strong>
Cache: 2000 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, <strong>-RAM</strong>, -RW, +R, +RW, +R DL
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No
. . . the version that is available in Europe and Asia and it registers as Apple shipped and supported. It only cost me about $40. I'm looking at the DVR-111 (115 at the rate they are pumping them out and I get around to it) or a Lightscribe (only LaCie has the label burning software for the Mac) for my second optical bay.
We own a DVD-RAM recorder from panasonic and have done so for a couple of years.
By far and away it is the best format for home DVD recording from the TV, the speed and flexibility (time-slip, instant erase, instant record ) is just amazing.
If anything, I would say DVD-RAM is getting more popular, it is now turning up on LG brand video recorders, toshiba laptops. Combined with a HDD its the best of both worlds (to my mind) for home video.
The only thing I can't get its the RAM recorded on panasonic to play back on my new MacBook (which is how I found this post via google)
I first became acquainted with DVD-RAM when I bought a Toshiba Satellite laptop back in 2002. Of course, it only read DVD-RAM discs. At the time, I didn't know what it was and I wasn't quite concerned with it. Although, it did peak my curiosity so I did a little research into this DVD-RAM thing and when I discovered that it works like a floppy and stores data like a hard drive, I was bummed that my optical drive could only read DVD-RAM discs. When I went shopping around for a new laptop I knew I wanted one with an optical drive that not only read DVD-RAM discs but that also writes. That’s when another Toshiba Satellite entered my view. I studied its specs and sure enough it had what I was looking for. I immediately purchased it. Then, after bringing it home, it occurred to me, I didn’t buy a disc. I went back to the store to get one. I couldn’t find any so I asked a clerk where I could them; he thought I was asking for SDRAM. I explained that they are like DVD±R/RW; it’s just that the word RAM takes the place of the ±R/RW that comes after DVD. He said he didn’t know what I was talking about and that he never heard of such discs. He continued to direct me to the SDRAM aisle. I looked around online for the discs but all I could find were discs for old drives that were incompatible with my drive. I gave up.
Some months later, I was in the market for a DVD recorder with a hard drive. There weren’t many at the time that had both. I told a salesman what I was looking for, and, so, then, he directed me to this RD-XS32 Toshiba recorder. I bought it, brought it home and to my surprise I discovered its multi-drive included DVD-RAM support plus there was a DVD-RAM disc in a Type II cartridge that I had found in the box. I was ecstatic I was finally going to satisfy my curiosity once and for all. It was everything I expected and more. I love the timeslip feature and being able to delete scenes and not have to reformat the disc in order to rerecord on it.
I am also noticing lately that DVD writers for computers come in 12Ч DVD-RAM. Now, if only the media were readily available.
Yep I'm based in the UK and have owned a Panasonic DVD recorder for a couple of years now. I've been using DVD -R but decided to try the DVD RAM disc for the first time today.
The first obtacle was to track down the discs as unlike, the ubiquitous DVD RW disc you can't buy these in a supermarket!
I went to a specialist computer shop, and was amazed that all 2 of the staff had never heard of DVD RAM, a third man in the shop had a vague idea, asking me don't they come in cartidges?
He added you are the first person to ask about this, mind you the shop has only been there for about a year, but even so!
Several shops later I managed to finally track a pack of the rare discs down, I made it my mission to track those elusive DVD Ram disc down but I can imagine the average DVD recorder user would have given up on trying the all singing and dancing DVD Ram discs that are described in the Panasonic manual. It's not suprising that DVD Rams aren't the disc of choice even with DVD Ram enabled DVD recorder owners, they can't find the damn things to try in the first place!
