- We are investigating the possibility of getting rid of our CDC 9766 drives
- (yeah, I know they're old! :-) and putting a rewritable magneto-optical drive on
- a Vax or PDP-11 using a CMD (SCSI) controller in their place.
-
- We want to use it as for long term data storage that needs to be accessed once
- in a while, and as a backup device, probably using 10 disks in a daily rotating
- incremental backup.
-
- Does anybody out there have one? If so, what is your opinion of it?
- I have seen some literature on the Ricoh Hyperspace 3600 - has a 37 ms average
- access, 28 ms average seek time, and gets 326 mb's per side/632 mb per disk.
- this sounds like what I need.....
-
- Some of the specs are that they (the media) last for 10+ years and can be used
- for 10^6 for write/erase passes. I figure 1 million passes should let you use
- the disk for quite some time :-)

- Thanks,
