Abstract

PURPOSE: To prevent a magnetic head from colliding against a recording medium by loading the recording medium with the magnetic head through linear type electromagnetic drive means which has its current supply controlled.
CONSTITUTION: When a power is supplied by linear type electromagnetic drive means 13, a plunger 19 is raised to a preset position. Then, a magnetic head is moved down together with a carriage by the action of a link mechanism 6 so that a recording medium is loaded with the magnetic head. If the current supply of the means 13 to a coil is controlled such that the suction of the means 13 takes its maximum at the start position of the plunger 19 and its minimum at the uppermost position, the loading speed of the head is so controlled that the head can be prevented from colliding against the recording medium upon the loading operation.
