Magnetic head device

A magnetic head device comprising:

• a cartridge holder for holding a cartridge in which an information recording medium is received;
• a magnetic head comprising
• a cantilevered supporting member having one end serving as a fastened end, the other end serving as a free end and a supporting member elastic portion between the fastened end and the free end, the fastened end being attached to a joint member moving in a direction substantially in parallel with a surface of the information recording medium, and
• a head main body that is attached to the free end of the supporting member and applies a magnetic field to the information recording medium;
• and
• a magnetic head holding member that is cantilevered by the joint member so as to extend from the joint member toward the head main body substantially in parallel with the surface of the information recording medium, is opposed to the information recording medium with the supporting member interposed therebetween and has an elastically deformable elastic spring portion near the joint member;
• wherein the magnetic head has a first position in which the head main body is located close to or in contact with the information recording medium so as to perform recording or reproducing, a second position in which the head main body is away from the information recording medium and a third position in which the magnetic head and the information recording medium are inclined while being kept substantially in parallel with each other so as to allow the cartridge to be mounted into or removed from the cartridge holder,
• the magnetic head holding member comprises a position holding portion protruding toward the information recording medium on the side of the joint member with respect to the head main body in a longitudinal direction of the magnetic head,
• a hole is formed in a region of the cartridge holder where the movement of the joint member causes the position holding portion to move,
• the cartridge is held in the cartridge holder, and when the magnetic head is in the first position, the position holding portion passes through the hole and then contacts the cartridge.
