ABSTRACT:
A temperature compensation technique for memory disk pack systems used in data processing apparatus wherein the temperatures at the base plate and at the disk pack are monitored so as to generate a temperature compensation error signal. Such error signal is supplied to the feedback path of the record/read head position servo loop of the disk pack system when the record/read head has moved to within a selected distance of its commanded position. The overall disk system is enabled only when the temperature error has stabilized to a value below a preselected level.
