Notes on using the LS240 superdisks
The LS240 drive supports the use of standard 3.5” disks with 1.44 Mbyte capacity
as well as superdisks with a capacity up to 240 Mbyte.
The track density of superdisks is 10
m
m as compared to 120
m
m with standard
disks.
The LS240 drive detects the presence of a superdisk and switches to the higher
capacity.
Due to their higher capacity, superdisks are more sensitive to dirt, temperature
fluctuations and shocks than standard disks.
Notice
Observe the following to ensure reliable operation and high degrees of data
integrity:
S Keep and transport superdisks in the protective cassette provided. This
protects the data medium from dust and dirt.
S
Only remove the superdisk from the drive when no reading or writing
operations are in progress. The data medium is protected from particles of dirt.
Do not expose the data medium to unnecessarily high operating temperatures.
Notice
When operations are in progress using the superdisk, avoid vibrating the unit.
Superdisks are more sensitive to vibrations due to the higher track density.
Emergency eject:
When the unit is switched off, the disk can be ejected by inserting a pinted object
(e.g. straightened paper clip) in the relevant opening provided.
