Abstract
A method and an apparatus for indexing a transducer head, such as is used in magnetic tape recording, is disclosed. A transducer head is mounted on a head carrier. The carrier supports a cam follower and the carrier and cam follower are resiliently biased against a cam. A gear train, including both a motor and the above-mentioned cam are mounted on a common support device. The support device is pivotally mounted. The head can consequently be initially indexed to a given track on the tape by pivoting the support device; this has the effect of moving the entire cam up and down and consequently the head as well. Once the head has been indexed to a given track it is moved between the various tracks by rotating the cam via the gear train.
