Just saw a short note in a local computer publication:
"Hitachi Maxell has announced a 3.5-inch floppy disc
with 12.5-megabyte storage. To be manufactured and
sold by NEC, it will be released in the middle of this
month"
Unfortunately no mention of Price,Performance,Availability.
Gadzooks Batman, obviously not as fast as a hard-disc but very
interesting.
Does anyone else have any more information on this beasty?

It was probably a typo for 1.25MB. Did it say _which_ month?

12.5 Mbytes is probably a typo. I doubt they could physically do
that!

I picked up data sheets for a 3.5" 4Mb Toshiba drive at Electro '88
a few months ago. They use perpendicular recording techniques to
get the high bit density, but you have to use special disks with a
new type of coating.
So it wouldn't surprise me if someone else has pushed the density
up a few more notches. The theoretical limit of perpendicular
recording is quite high.

| 1525.4 | Supra 10MB floppy | VTHRAX::KIP | No Dukes. | Mon Jul 11 1988 13:48 | 14 |
I've seen in a flyer from Supra:
SupraDrive FD-10 Removable Floppy Drive
---------------------------------------
Our 10MB removable floppy disk drive will soon be available for
Amiga and Macintosh computers. The Amiga version will require a
SCSI interface adapter (or our Amiga SupraDrive hard disk) to connect
to the computer. The Macintosh version plugs directly onto the
Mac's SCSI port and will work in conjunction with hard disk drives
or by itself.
The flyer is copyrighted 1987. They list the FD-10 as an Amiga
500/1000 product (works with 2000????) @ $895.00. Elsewhere they
list diskettes for the FD-10 @ $39.95 each.

from ESD: The electronic systems designs trade magazine,
july 88 p 17
Maxtor has achieved a 200-Mbyte formatted capacity in the LXT-200
and 760 Mbytes in the EXT-8760, using thte same technology for both
3 1/2" drives. The LXT-200 squeezes 4 platters into the 1.6" gap
available for half-height drives, but surpasses the 760-Mbyte drive
in areal density. Trac density for both is 1376 tracs/inch, while
linear density is more aggressive for the smaller drive (31,596
bits/inch versus 31,429 bits/inch)....
More conservative in approach, but achieving similar results, is
Quantum's Prodrive 170. This drive has a 168-Mbyte formatted capacity
employing a more conventional ferrite composite head/thin-film media
comination in its four-platter design. Track density is 1000 tracks
/inch and linear density is 22,050 bits/inch using 2,7-RLL encoding.
