Usage notes for LS 120 Superdisks

In Floppy disks up to 1.44 Mbytes as well as Superdisks up to 120 Mbytes can be
used in LS120-drives.
Track density for Superdisks is 10 mm compared with the 120 mm of conventional
disks.
The LS120 recognizes when a Superdisk is in the drive and switches to the higher
capacity. With conventional disks, a capacity of 1.44 Mbytes or 720 Kbytes can be
reached.
Due to their higher storage capacity, Superdisks are more sensitive to dirt, tempe-
rature and shock than conventional diskettes.
