Claims

[Scope of utility model registration request]

In a mechanism that brings a permanent magnet erase head into contact with a magnetic tape during erasing or recording, a magnetic field generated by passing a current through a solenoid coil provided on the outer periphery of the permanent magnet erase head acts on the magnet, causing the head to An operating device for a magnetic head, characterized in that the contact is made by raising the magnetic head.
