ABSTRACT:
In a data transfer apparatus such as a Winchester disk drive wherein a transducer or transducers fly over a magnetic disk surface or surfaces during data transfer therewith, a retractor mechanism is provided which coacts with a transducer positioning mechanism for causing the transducer to land on a head landing track disposed radially and inwardly from a series of concentric data storage tracks on the disk, as when the apparatus is electrically turned off. The retractor mechanism includes a spring or like energy storage element in which energy is stored when, with the apparatus powered on, the transducer is first transported by the positioning mechanism from the head landing track to the outermost home track on the disk for initialization. The spring is locked, as under the force of a solenoid, against the release of the stored energy during the subsequent run of data transfer, making it possible for the positioning mechanism to transport the transducer from track to track without being loaded by the deflected spring. When the apparatus is powered off, the solenoid unlocks the spring for releasing the stored energy and hence for returning the transducer to the landing track.
