ABSTRACT:
A magnetic head positioning apparatus including a chassis, a driving device provided on the chassis, a guide member provided on the chassis, a carrier movably provided on the guide member, a first metallic head support mounted on the carrier and adapted to support a first magnetic head, and a second metallic head support mounted on the carrier and adapted to support a second magnetic head which is disposed to oppose the first magnetic head. A coupling member is formed on the first head support and directly connected to the driving device. By moving the coupling member by the operation of the driving device, the carrier is moved along the guide member through the first head support. Thus, it is possible for the magnetic head positioning apparatus to possess excellent resistance to environmental changes and to effect highly accurate positioning of the magnetic heads.
