24-bit animation being an absolute pig for memory, storage and frame accurate recording capability, I'm considering attacking the second with a large capacity eraseable optical drive. Does anyone out there have any experience with these beasts? I've done some checking around, and the Ricoh 640 MB unit ($1899 internal, $2499 external, $349 per cartridge) seems to be about the best buy. I'd be using my GVP 33 MHz '030 Series II accelerator/SCSI controller board to talk to the drive. There are some 1 GB units around, but they seem to start at around $3500 (although cartridges are no more expensive than the 640 MB ones). I'd appreciate any experience others have had (successful or otherwise). BTW, as for the third obstacle mentioned above, the best (but not cheapest!) solution I've seen is a recordable laser disk machine. Sony makes one (about $20,000!!) that takes composite, component or RGB video input/output. Panasonic makes one (even more $) that is eraseable. These guys hold 40-50000 frames (25-30 minutes) on a cartridge. Best part is – NO wear and tear on the transport mechanism of a very expensive tape-based single frame recorder. Also, essentially no generation loss, as the incoming video is digitized and stored in binary format. Oh well, I can always dream… Thanks, Joe Pizzicaroli

I've been using an older Panasonic optical recorder for a week or so no. Its the Model 2200, and is about 6 years old. On its 8 inch disc it can record about 15000 frames – with discs costing around $170 each. The image quality is okay, although not as good as one would get with more modern VTR's or laser recorders. It works with lightwave (video toaster) too. I got it used (of course) for around $3500…. Lou p.s. On the subject of optical drives you might want to look at an article in AmigaWOrld about a year ago…three models were compared.

Are you saying it delivers VHS, S-VHS or Hi8 quality? When it doesn't deliver, what does it do?

Lou – Thanks for the reply. The price sure is right on the unit you refer to, but I'm bidding on a job for a client who insists on nothing less than TRUE network broadcast quality. His studio is built around Betacam SP gear, and from what I've looked at, new decks of that format start at around $20,000 and rapidly get up to $35,000 or so (OUCH!!!). That's why I thought that recordable laser disk was a viable alternative. The SONY unit I mentioned inputs and outputs NTSC composite, component, Y-C and RGB formats. As for eraseable optical SCSI hard drives, thanks for the reference. I'll go back through my AmigaWorld archives and look for the article you mentioned. – Joe

Joe, I was told by a guy at AmiExpo (attendee, not a company rep) that ther is a 1gig RW optical available for the Mac at just under $1000. He said he was getting one for his Amiga. It is a scsi using standard cabling and should work off a GVP accelerator. I haven't had time to check on it yet, though, so I don't know if it is real or not. wmc

Sounds too good to be true at that price. If you find out more, though, let me know. The products and pricing in this area are changing so fast that it's hard to keep up. Thanks for the response. – Joe

I checked one local Mac dealer and he had nothing on it. So I assume it was a misstatement. The closest I found was a 1 gig dat for 1300. wmc

Wayne – Thanks for checking it out. The best value I've come across so far is a new unit from Ricoh, the HyperSpace. This is a 5 1/4 inch SCSI eraseable optical 650 MB cartridge drive. It's pretty fast, too – 37 ms average access time and a 1 MB/sec sustained transfer rate. It goes for about $2850 and cartridges for about $180. Still not cheap, but I figure in the long haul it'd be more cost effective than a big hard drive, or Syquest or floptical drives. – Joe

Joe, I'm inclined to agree with you. Just have to find an interim place to store all the animations and art that I need to create/sell to pay for the Optical RW drives! wmc

Wayne – Sounds like a familiar story. I've been buying floppy disks in bulk quantities, but it's really a pain to see a 10-second HAM animation sequence eat up 20 or 30 disks (for the IFF frames themselves AND the anim delta files). Then when it's time to record to video tape, it's an excruciating process of loading stuff from floppy until the hard disk is full, recording to tape, purging and doing it all over again until all the stuff is recorded. I can't even conceive of doing 24 bit work without massive storage capability, but I'm painfully aware of the chicken-and-egg problem to which you refer. Like you, I'm trying to bootstrap my capability a little bit with each paying job. Hopefully, one day, these crude techniques and mountains of floppies will be but fond memories. – Joe

Actually, check recent issues of MacWeek for a cost/meg comparison between Syquests, 120 M opticals, and 600 M opticals. The 3 1/2 120 M opticals make sense if you're buying more than a dozen Syquest carts. The 120M drives are about $1900, with disks about $25.

John – Thanks for the heads up – I wasn't even aware there were 120 MB optical drives. The price sure sounds good. I figure that one upcoming project is going to produce around 1 Gig or so of 24-bit IFF files, so even at $25/disk, that's only around $250 on top of the cost of the drive. On that basis, it sounds more cost effective than a 600 MB optical drive. I'll try to dig up some recent MacWeek issues and scout around. In case I don't turn anything up, can you give me any leads on who makes theses 120 MB drives? Thanks in advance, – Joe

You'll find them. I think Sony makes one.
#18739From: Joseph C. PizzicaroliApr 27, 1992 8:39 PM
John – Thanks. I just came across an ad in the May issue of PC/Computing for a unit by Pinnacle Micro. It's a 3 1/2 inch 128 MB unit and uses the Sony drive mechanism. List price is $1995 and cartridges are $79. Not bad, I'll seriously consider it. – Joe

ya can get em from Creative Computers I Believe

Peter – Much thanks for the info. I've dealt with Creative before and had good luck with them. – Joe

Always Glad to help Joe.
