#Magneto-Optical Drives
7 messages in this thread
Hi!
I am looking into magneto-optical (MO) drives and would like to hear some
feedback on them…especially when used for daily data retrieval instead
of just backups. (Essentially, I am running out of hard disk space on my
portable – it's already STACked – and am exploring ways to augment my
storage. SCSI-2 would be the perferable interface, since my portable
already has a built-in port.
I would primarily use a magneto-optical drive to create and store
projects from 3D Studio and Ventura Publisher.
What are the advantages/disadvantages of the 3.5 vs. 5.25 MO drives? (I
understand that 3.5 drives hold 128 MB while the 5.25 holds 600 MB (300
MB/side) – but that the 5.25's are signifcantly slower than the smaller
format). What manufacturers/models would you recommend? I have seen ads
for drives by Pinnacle Micro, Sony, Peripheral Land, Procom Technology,
MicroNet Technology, and Mass Optical Storage Technologies (MOST). MOST
claims to have a "free form" mode that stores 256 MB on a 3.5 MO disk,
but what is "free form" and what does this proprietary method mean for
compatibility? Can MO drives be STACKED? STAC Electronics thinks they can,
but doesn't seem to know for sure. And finally, what other issues or
technologies should I consider?
Again, my primary aim is additional secondary storage… I am attracted
to MO since it seems to offer both reliable backup and "unlimited"
secondary storage – all through a SCSI-2 port.
Thanks in advance!

There is a standard ANSI/ISO for the 128 meg magnetic optical drives so
they are supposedly compatible between everyone. The drive is around $2000
and the carts (128meg) are similar in price to Syquest carts … (by the
way IBM and a group of 9 vendors came up with the ANSI/ISO standard to try
to unseat syquest as the king of removable media). The speed is supposed
to be under 30ms and I have heard claims to 9ms.
The other formats 600 meg drives have little or no standards I guess their
is a sony standard somewhat. But interchange between these drives is very
questionable.
Albert,
Thanks – I didn't know that the 600 meg carts didn't follow a standard… I
guess that's another reason to go with the 3.5" drives.
Thanks.

There is an ISO standard for the 600meg MO drives and currently all 5 1/4"
MO vendors support it.

Thats nice to know that some standard exits.
Two suggestions!
Low End = Bernoulli 90mb Transportable. Great interfaces, MAC SCSI, PC
SCSI, and Parallel. Cheap and fast enough as an added drive.
High End = Storage Dimensions 1gb Read-Write Optical Disk Drive, 500mb
each side. Works great if you can afford it.
I love the hi-end 1 gig carts!
