Usage Notes for LS240 Superdisks
Floppy disks up to 1.44 Mbytes as well as Superdisks up to 240 Mbytes can be
used in LS240 drives.
Track density for Superdisks is10 mm compared with the 120 mm of conventional
disks.
The LS240 drive recognizes when a Superdisk is in the drive and switches to the
higher capacity.
Due to their higher storage capacity, Superdisks are more sensitive to dirt,
temperature and shock than conventional diskettes.
Notice
In order to achieve a reliable operation and high data security, please note the
following during use:
S Store and transport the Superdisk in the protective cassette included. This will
keep dust and dirt from the disk.
S Remove Superdisk from the drive when it is not being read or written to keep
dirt particles away from the disk. Do not expose the disk to unnecessarily high
operating temperatures.
Notice
If possible avoid vibration of the device, when using Superdisks. Superdisks are
more sensitive to vibration as a result of their high track density.
Emergency Removal:
When the device is switched off, the disk can be forced out by using a pin (for
example, an opened up paper clip).
