Anyone got a price, release date, interface, transfer rate, track capacity (gives a whole new meaning to track at a time buffering), latency, etc. rumor to share? This is just the right sized storage for my home system. Think of it as room for a five year supply of Fish disks (assuming the current acceleration in releases continues), plus the workbench, and including the mg editor, arc, zoo, uuencode, uudecode, patch, unshar, and a few other vital tools (like Bard's Tale II and III, for those idle download hours, (WHERE are the Amiga versions?)), [or one day of comp.pictures.amiga postings, take your choice! ;-) ] This could make virtual memory pretty popular in home systems, too, at the right price. ------------------------------------------------------------------------------ | From: sxm@philabs.Philips.Com (Sandeep Mehta) | Newsgroups: alt.emusic | Subject: erasable optical disk (Re: Hello?) | Date: 8 Jun 88 11:59:53 GMT | Reply-To: sxm@bebop.UUCP (Sandeep Mehta) | Organization: Philips Laboratories, Briarcliff Manor, NY | | In article <10642@agate.BERKELEY.EDU> mellon@eris.berkeley.edu (Ted | Lemon) writes: | >I'm here.

Way to go! That's a heck of an accomplishment in a mechanical system in so short a time. Kent, the man from xanth. Of course, you'd have to have two drives; nothing else is suitable for backups, and doing a one drive backup with 12 megabytes of Amiga memory is 84 or so disk swaps; bad case of swappers' shoulder from that little trick.

No no no, what you do is build yourself a large circulating memory device. Take one high powered lasers and small amount of buffer memory. Point the laser at the moon and look for the reflections. Now it's about 246k miles to the moon if you allow about two thirds of this for active data time that gets you about two seconds worth of data. If you can tramsit at ~1Gbs thats 256k bytes or so of data storage. You should be able set up a data framing format such that you can insert a lump of data and let it circulate for any amount of time while you swap disks. This has several dis-advantages over using large mos-memory devices, some of which are quite attractive. 1. You have to swap the disks far more often, thus reducing the likelyhood of actually doing a backup. 2. Your electricity bill would quite high, thus increasing the profits of the service provider which then requires that the provider pay more tax thus reducing direct personal tax,right. 3. It only works when the moon is out, full-moon might be appropriate. 4. Data integrity could be as good as a telephone line. 5. Increasing the systems bandwidth would cost heaps. I'm not sure how but you should be able to find a way of using multiple links. So if one was to build a system with about 4000 lasers you could store the entire contents of the cdrom in one lump. This does of cause contradict point 1. 6. You would probably have to buy a small lump of the moon in order to have an area to yourself. This could lend to great advances in commercial space flight, you know the odd trip to talk over the deal with the real-estate agent etc. 7. Your data would still get mixed up with every one elses'. A great boon for the anti-privacy lobby. 8. Network traffic would be greatly reduced as everyone could `see' all the other data, `look and you shall see??' jon -- Jon Wells @ O'Dowd Research P/L.

It should also work if there is no full-moon, after all, what do you have your computer for?

This will only work for restricted regions, for (a) to be able to `see' you have to have the same light conditions as the originating MELSD site (i.e, night). (b) due to the diffusion angle of our nowadays lasers the distribution of news or any network items will be limited to certain regions only. > > jon > > > -- > Jon Wells @ O'Dowd Research P/L.
