Abstract

A device for positioning magnetic heads over preselected tracks on magnetic disks in memory processing units, the device consisting essentially of a linear electric motor, including a stationary, partially hollow magnetic device, and of a support member and a guide member which is mounted on the latter in an axially movable manner and is provided with at least one head mount for at least one head support, wherein the support member is mounted at one end of the magnetic device and is otherwise unsupported by the chassis of the memory processing unit.
