ABSTRACT:
According to the subject invention, the correction for thermal mistracking may be achieved by the incorporation of a compensating plate in the carriage, the plates' length and coefficient of expansion being selected to nullify the off-track shift with temperature.
Mistracking which varies from the outside to the inside track, i.e., there is a change in stroke length of the carriage with temperature, is compensated for by selecting a pulley material from a material having a coefficient of expansion directly related to the coefficient of expansion of the material of the disc. The result of a proper selection is that the change in size with ambient temperature of the disc is correlated with the change in size of the band with the same temperature, so that the total effect is as close to a nullity as possible.
