Abstract
A random access information storage disk drive system of the optical or magneto-optical type with the read/write head mounted between parallel flexures for suspension in a linear actuator motor. Dynamic spring force compensation is provided incrementally as the head is moved radially inward and outward of the at-rest position of the flexures to compensation for the increasing restoring force exerted by the flexures as the head is moved towards the extremes of its tracking path.
