Transducer head indexing device and method.

摘要

A method and an apparatus for indexing a transducer head, such as is used in magnetic tape recording, are disclosed. A transducer head (30) is mounted on a head carrier (29). The carrier supports a cam follower (28) and the carrier and cam follower are resiliently biased against a cam (19b). A gear train, including both a motor and the above-mentioned cam are mounted on a common support device (12). The support device is pivotally mounted. The head can consequently be initially indexed to a given track on the tape (31) 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.
