録再生装置の磁気ヘツド移動機構。 A device is equipped with a magnetic head in which a loading member pulls out a magnetic tape from a cassette, fills it into a predetermined tape path attached to a guide drum, and runs the magnetic tape along the tape path for recording and reproduction. A movable magnetic head support member, and a first shape and a second shape that are different from each other are stored, and the change to the first stored shape causes the magnetic head to move away from the magnetic tape in the tape path. The magnetic head supporting member is moved to a position that does not interfere with the movement of the loading member, and the change from the first memorized shape to the second memorized shape causes the magnetic head to move toward the magnetic field of the tape path. In order to move the magnetic head support member so as to come into contact with the tape, a shape memory member is attached to act on the magnetic head support member, and a shape memory member is attached to a first shape memory member depending on the situation of the magnetic recording/reproducing apparatus. 1. A magnetic head moving mechanism for an automatic tape loading type magnetic recording/reproducing apparatus, comprising means for controlling the temperature of said shape memory member so as to selectively take a memory shape or a second memory shape.
