Abstract
A magnetic head actuating mechanism including a capstan attached to the shaft of a magnetic head driving motor, and an actuator arm supported on a pivot, adapted to be turned through a thin metallic band by the capstan and mounted fixedly at one end thereof with at least one magnetic head. The magnetic head actuating mechanism is designed so that the moment of the unbalanced mass of the turning assembly thereof about the pivot is within the predetermined range. The magnetic head is held stationary even while the magnetic head driving motor is not energized. Thus, the magnetic head actuating mechanism obviates the injurious state of contact between the magnetic head and a magnetic disk easily and need not have any magnetic head locking mechanism.
