ABSTRACT:
An improved magnetic tape drive having high performance specifications is achieved by microprocessor control of the capstan motion. Possible velocity profiles are stored in read-only memory and are selected on the basis of new input commands and last previous actions taken, whereby excitation of mechanical resonance inherent in the system is avoided.
