Abstract

Abstract A miniaturized cartridge-type tape drive for data storage applications has a main support frame upon which is mounted a tape-drive motor and a transducer-positioning motor, disposed one behind the other. Both such motors preferably have generally flat silhouettes and are directly-coupled to corresponding actuating members: a tape-driving capstan for the tape-drive motor, and a rotary positioning cam for the transducer-positioning motor. An elongated transducer-positioning linkage arm (40) extends from the rotary cam, to the transducer, and is pivotally mounted (42) in mounts on the frame. The arm is biassed into contact with the cam at one end (48), and the transducer at the other (52), by means of a spring (54).
