Abstract
The present invention provides a cleaning apparatus for cleaning the air bearing surface of a magnetic head of a tape drive by employing components of an actuator for oscillating the magnetic head against bristles of a brush assembly. Circuitry is provided which senses the appropriate time to commence the cleaning action and continues the cleaning action for an appropriate duration when the magnetic tape is off the magnetic head. The circuitry causes the actuator to move the magnetic head in oscillatory motion against stationary bristles of a brush assembly which are selectively brought into engagement with the magnetic head. The engagement and disengagement of the bristles with respect to the magnetic head are implemented by a lever arm which has camming surfaces which are engageable with a leader pin which moves a leader block and magnetic tape about a guide and across the magnetic head.
