[comp.sys.amiga.tech] A590 w/Panasonic 11meg FD

michael.hainsworth@canremote.uucp (MICHAEL HAINSWORTH) (08/07/89)

Hi there! I recently read in a reputable magazine that Panasonic has
released a 3.5" Metal Floppy Disk drive that will hold up to 11
megabytes.  I'm curious to know if this drive is available yet (in the
USA or preferably Canada) and if it can be hooked directly to an Amiga
590 Hard drive (This is the A500 hard drive from CBM).
 
Any news or ideas?  The A590 has a SCSI connector, and I believe it's a
25pin?
 
Thank you in advance,
Michael Hainsworth

InSite Peripherals in San Jose is also beginning to ramp up production
on their 20.8M Floptical Drive. The drive is a 3.5" form factor, SCSI
interfaced drive that takes 3.5" floppies that have one side "optical"
(which is really just a bunch of hard coded servo tracks) and the other
side magnetic. The Drive mechanisims will probably be retailing for 
something like $500 - $600, and the floppies themselves are $100 for
a box of 5 ($1/Meg). They claim they will be in volume production 
next month.

No as for hooking it up. The hookup should be straight forward since
they are SCSI and the SCSI drives out there today all work. There are
two areas that will need further attention. 
	1) Formatting, the first time you use a floptical you will 
	   have to hard format it. That means sending it a hard format
	   command and most scsi drivers don't do that when you use
	   the AmigaDOS format command. ('cuz it's faster to use QUICK)
	   Generally though, people like Cltd and Microbotics have a 
	   utility that will format those puppies by sending the SCSI 
	   command.

	2) The other area is in ejection. FFS in 1.3 doesn't know how to 
	   eject a disk (No DiskChange stuff in the handler) and most
	   scsi drivers just stub out the trackdisk compatible diskchange
	   stuff because the media isn't changeable. 

If Randell or whomever in C/A is responsible for those things has dealt
with those issues then it should be a simple matter of plugging in the
wires. Otherwise, you may have to hack around a bit.

The Panasonic 11 Meg drive is, as far as I know, real.
Some claimed specs:

640 tracks per side, 35,000 bits per inch
16 MB unformatted, 11 MB formatted
2 Mbits/s transfer rate
SCSI interface, self-formatting
Average seek <60 ms; track-to track 10 ms
Can read (but not write) 1MB and 2MB disks
"micro-stepping" motors give high speed and 2 um tracking accuracy


Evaluation units supposedly available in July, and a list price of $250.

The info I have has this address attached, but it's not labeled
as a "contact address" or anything:

Yes, the 11meg floppy is real.  It's been in production since June 1989.
The bad news is: NCR (a certain big and powerful company) has exclusive
rights to test and use the JU3511. In another word, they HOG the whole project
during the first year.  Panasonic also would like to see how this product 
would fare through NCR first before releasing it to other OEMs & distributors.
Last time I talked to the sales manager who handles the JU3511, he said I
wouldn't see the drive anywhere else (except NCR) until July 1990.

I can't even get my hands on any application manual for the drive and I
WORK for the Panasonic disk drive division.
