Rick, One of the local papers printed a paragraph article about something called Thor CD that they said Tandy was working on. It is supposed to be a way of writing AND erasing an optical CD. Have you heard anything about it? It would seem to be an ideal way to turn the Amiag into a digital recorder (2, 4, 8, 16, 24, 32 track) if it can hold data in the quantities of other optical mediums. Of course we would still need the sampling harware first. Barry 8)

Not offhand, though… but that doesn't mean it doesn't exist. Probably someone else can shed some light? <Hint hint> Rick

The copy I saw said that the computer version would be available 'within 3 years'. Also noted that the 'recording publishing' industry was all upset (what else is new) about such a product.
#120718From: Barry MassoniApr 24, 1988 4:48 AM
The article I read said 1 year to 1 1/2. Of course this gives harware developers a chance to get ready and create a monster sampler for the Amiga. I can see why they're upset-if you were selling digital tape recorders for $250,000 (thats two-hundred fifty _thousand_ dollars) you probably wouldn't like it if it became possible to do the same thing for 4K. [I'm refering to the Sony and Mistubishi multi-tracks <24 and 32>]. Barry

A pox on the 'recording/publishing' industry!!!! I'm sure that the monasteries were extremely upset by the discovery of moveable type. It's a good thing lawyers were more scarce in the old days, otherwise the dark ages would have lasted a few more centuries <grin> Bring on new TECHNOLOGY!!!! -RSL-

I read about Tandy Corp.'s Thor CD technology in a local newspaper (Daily News, New York). If the report is on the level it promises to revolutionize memory storage technology (imagine having a $500 drive which stores interchangeable 500 megabyte disks at $15!!!!!! The article compared the Thor CD technology with VHS technology! I scaned CIS' CDROM forum, and they hadn't mentioned it yet! I left a message asking if anyone out there heard about it. The technology is still 12-16 months away from a consumer product, but I hope it works!!!!!! -RSL-

I hope it works too! Tandy has had the guts to announce a PS 2 clone (big deal, I know) but at lease they're seemingly out to play with the big boys. Thor CD could make them another Sony. Lets hope they don't price it out of the market. Imagine selling one to everyone that has a computer for a few hudred dollars instead of selling a few thousand for a few thousand. Bary that should read "Barry" and lease should read "least" 8)

The prices quoted by Tandy are almost as exciting as the technology. The say that the player/recorder should be priced at $500 and the replaceable disks will retail in the $10-$15 range!!! This single advance will kill present hard disks if it appears in the market place as predicted!!!!! -RSL-
#120751From: Vic WagnerApr 24, 1988 1:29 PM
I don't think it will 'kill' present hard disks. CD data rates are VERY slow by comparison to current HDs, the access times are also slow. If you want a sample of how slow the access times are, try telling your audio CD player to go from the first song to the last on a disk. Access times are in the .5 second range, HDs are in the .020 second range. Data rates are around 600K bytes per second and up for HDs and 176.4K bytes per second for CD. At least thats the info I have on them at this point.
#120871From: Roy S. LauferApr 25, 1988 9:06 AM
Read Tandy's suggestion that technological innovations being worked on today will bring CD seek times up to and beyond that of hard disks! Even if CD technology is slower, hard disks will be relegated to a high speed cache for your CD storage! (Until memory prices dive down and high speed megabyte CD cache systems become cost effective! True, its all vaporware… But its EXCITING VAPORWARE!!!! -RSL-

There is no doubt in my mind that if people want it badly enough, CD access times begin to approach those of HD's. They need to reduce the mass of the lens system considerably, but I was reading only a few weeks ago about research into using holographic lenses.
#121024From: Roy S. LauferApr 26, 1988 5:13 PM
Tandy's product announcement mentioned work on holographic lenses as the future advances that will bring up CD's seek times upto and beyond those of present hard disks. It looks like optical technology is going to push magnetic technology into better and better specs (not to mention price/performance ratios)!! I can't wait to see what the industry come up with when people start complaining that 'the old 500 megabyte disk capacity just isn't enough'! Remember when we were all thrilled to have an 8 bit CPU with 2K of memory??? -RSL-
#120783From: Steve AhlstromApr 24, 1988 6:10 PM
I wouldn't go a far to say the new technology will kill off HDs. Access times on laser disks are SLOW. There is no such thing as track to track since they only have 1 spiral track. A getting from point a to point b is time consuming.
#120795From: Doug WingerApr 24, 1988 7:02 PM
Roy, Not quite. They're a bit slower from what I read. They _will_ make a nice second large-capacity storage device, though. A place to keep all those neat, big data files, like sampled sounds or graphics. It opens up a lot of possibilities. Doug

I remember reading about a fellow in the Bya Area named Thad Floryan, who had, at the time the AMiga was about 1 year old, over 1400 disks full of Amiga related stuff. It comprised literally everything that he could get his hands on; text files, programs, source code, messages on BBS's, etc. Imagine putting all that on 3 500 meg CDs… of course finding anything would be a bear. -larry
#120846From: Doug WingerApr 25, 1988 1:11 AM
Larry, Welp, using his HD as in index would take care of that. 8) I remember reading about the CD Encyclopedia, and how 20 percent of it was set aside for cross-referenced indexing. The only drawback to having that much storage space is locating things. The first person that comes up with software for indexing in a rational manner is going to make _some_ money! Doug
#120937From: Jon BryanApr 25, 1988 9:16 PM
I believe that the overhead for the indexing is closer to 50%.
#121000From: Doug WingerApr 26, 1988 9:22 AM
Jon, You may very well be right. I do remember that a great deal of overhead was required just to make accessing what you were looking for a same-day task. That's the only problem with having gobs of storage space. Unless it is divied up in a logical manner, searching for a single item becomes a nightmare. As I remember, the method used in that particular case was search the index, and use that to find the actual information. Even while using the index, however, the time to look up something general was in the minutes range. Unless you knew what you were looking for specifically, which was almost painless, the search took a long time. Still, the thought of availability of all that storage for long-term files and permanent backups makes me drool. Doug
#120835From: Don Curtis/SYSOPApr 24, 1988 11:53 PM
Barry, The article I read said that Tandy was licensing the technology from IBM to create their PS/2 clone…so that's no big deal. Don
#120729From: Richard Rae/SYSOPApr 24, 1988 11:06 AM
There's a brief recap of the article in… duh… either the MusicForum or the MIDI forum. I think it's the former; check section zero, computer music. It's only a one paragraph blurb and it doesn't say anything that hasn't already been mentioned here, but thought I'd mention it in case anyone is interested. Rick
#120870From: Roy S. LauferApr 25, 1988 9:06 AM
I just read the official announcement from Tandy in DL14 on TandyPro Forum. There announcement promises a great deal, but I still don't have the slightest idea of the specs. Rumors I have read on CDROM Forum have quoted dissapointing specs of 100 MB per disk and only 18 writes. I don't know if this is the real specs (I hope not). In Tandy's announcements they say that their CD technologies seek times are compatible with present CD technology and advances being worked on promise to advance the CD seek times faster than magnetic hard disk speeds! Why do I have this sick feeling in the pit of my stomach that this announcement was written by 'marketing' instead of the 'technical' department! Let's all just hope for the best! -RSL- P.S. I never thought I would use the words Radio Shack (Tandy) and innovation in the same sentence!
