ABSTRACT:
An apparatus for positionally controlling the movable head assembly of a magnetic disc memory unit. In a first state, the head assembly is accelerated under substantially free conditions. In a second or deceleration state, the assembly speed is compared with and regulated by a series of theoretical speeds set in accordance with the actual speed attained by the movable head assembly during the first state.
