録再生装置。[Claims for Utility Model Registration] (1) In a rotating head type magnetic recording and reproducing device in which a rotating drum is provided with a plurality of magnetic heads and a magnetic tape is wound around the rotating drum obliquely to the rotating direction of the magnetic head and runs. The rotary drum is provided with a variable head position mechanism for changing the mounting height of the magnetic heads, and the variable head position mechanism allows the magnetic heads that are not used for recording to be moved to the magnetic tape by the variable head position mechanism. 1. A rotary head type magnetic recording/reproducing device, characterized in that a magnetic head which is set at a position to scan the next track on which recording is to be performed and which is not used for this recording is used as an erasing head. (2) The rotating head type magnetic recording and reproducing apparatus according to claim 1, wherein the head position variable mechanism is a piezoelectric element installed between the magnetic head and the rotating drum.
