    Abstract: PROBLEM TO BE SOLVED: To provide a cleaning device cleaning the air barring surface of the magnetic head to a tape drive by vibrating the magnetic head with respect to the bristle of a brush assembly by using the component of an actuator. SOLUTION: A circuit detecting the time suitable for starting a cleaning operation an continuous the cleaning operation for a proper time when a magnetic tape is separated from a magnetic head 22 is provided in this magnetic type drive. The circuit make an actuator move the magnetic head 22 with a vibrating movement with respect toe the fixed bristle 6 of the brush assembly and then the bristle 66 is made to be selectively engaged with the magnetic head 22. The engaging and disengaging of the bristle 66 with respect to the magnetic head 22 are executed by a lever arm 90 having a cam face capable of being engaged with a reader pin 46 moving a reader block and the magnetic type along a guide 24 and across the magnetic head 22.

    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.
