Abstract
A method of retaining a transducer for a digital storage apparatus that reads and writes data to a tape as the tape is moved in a tape drive path across the transducer. According to the method a head assembly is attached to the base to be movable relative to the base in a linear path that is perpendicular to the tape drive path. Movement of the head assembly is guided on a track that is partially defined by the head and partially defined by the base. At least two balls are disposed in the track between the base and the head assembly. A magnetic coupling retains the balls within the track. A linear motor operatively engages the head assembly to move the head assembly to follow the tape.
