Therefore, according to the magnetic field head elevating mechanism 37, the magnetic field head 35 and the disk clamper 36 are independently moved by sliding the magnetic field head slider 93 without depending on the elevating stroke S ₂ which is the elevating amount of the cartridge holder 29. Since it can be moved up and down, there is great freedom in design. That is, the lifting stroke of the magnetic field head 35 and the disk clamper 36 can be freely set by selecting the slide stroke of the magnetic field head slider 93 and the inclination of the tilt guide 100.

Further, the guide pin 97 of the magnetic head slider 93 is loosely fitted in the vertical groove 98 of the main slider 24, and the magnetic slider 9 is moved by the main slider 24.
