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 mm as compared to 120 mm 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:

SKeep and transport superdisks in the protective cassette provided. This protects the data medium from dust and dirt.

SOnly 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.
