Abstract: An apparatus for driving a magnetic head relative to a rotatable recording medium upon rotation thereof. The apparatus has a turntable for accepting the recording medium; a spindle for aligning the recording medium; a tripod for supporting the turntable; a tubular member for aligning the turntable, spindle, and tripod; and a flange connected to the spindle for causing the spindle to be lowered upon the lowering of the turntable. With a recording medium positioned on the turntable and rotated, a leadscrew connected, through a gear arrangement, to the turntable and the magnetic head will cause the magnetic head to be driven relative to the recording medium. When a new recording medium is to be placed on the turntable, the turntable is lowered; causing the tripod to engage the flange and thereby lower the spindle for facilitating removal of the original recording medium.
