Abstract
In order to provide a head transfer mechanism capable of absorbing a play of a head assembly not only in a thrust direction but also in a radial direction as well as a head actuator assembly and a tape drive using the same, the head transfer mechanism comprises a lead screw with a thread ridge, a head elevation guiding member, a preload bushing arranged in a hollow opened portion of a head lift, and a compression coil spring for applying the head lift with a pressing force in an axial direction of the lead screw. The head elevation guiding member comprises as an integral structure a head lift on which the head assembly is mounted and a head guide having a thread groove engaged with the lead screw and serving to move the head lift up and down along a rotation center axis following the rotation of the lead screw. In the head elevation guiding member, the head assembly is given a biasing load in a radial direction of the lead screw.
