ABSTRACT:
A magnetic head height changing apparatus is disclosed which is provided with a cam mechanism with a cam surface and claws, a pulley or gear device driven by a motor or fly-wheel and movable or rotatable to engage with or disengage from the cam mechanism, a first engaging device bearing a magnetic head and engageable with the cam mechanism, a second engaging device for locking the pulley or gear device when it is spaced from the cam mechanism, and an operating device for operating the second device. With the disclosed magnetic head height changing apparatus, when the second device is operated by the operating device to release the locking of the pulley or gear device and to make it contact with the cam mechanism to rotate the same by a predetermined value, the second engaging device again locks the pulley or gear device to stop the rotation of the cam mechanism to hold the magnetic head at a predetermined height.
