• Data recorded on a disc is read by laser beam, so there is no wearing of the disc due
to friction from a needle. You should handle discs carefully, however, as excessive
warping or scratches on the disc surface or label can lead to reading errors.
Precautions when Handling Map Discs
• Store discs away from direct sunlight.
The disc might warp and become
unusable.
• Lightly wipe the disc with a soft cloth in
a straight line from the centre of the
disc towards the outer edge.
• If you touch the data surface of a disc
(the surface without a label printed on
it) it might get dirty and lead to a
malfunction. Always hold a disc either
by its centre hole and an edge or by
two edges.
• Never clean discs with benzene,
thinners, record spray, anti-static spray
or chemical swabs.
• Do not write on, or stick paper or seals
onto, the surface of a disc.
• Map discs rotate at high speed inside
the main unit. Do not use a cracked or
badly warped disc, therefore, because
it might damage the main unit.
