ABSTRACT:
A tape recording apparatus has a chassis, a rotary head rotatably mounted on the chassis to record a signal on or to reproduce a signal from a magnetic tape in a tape cassette, a reel base mounted on the chassis for supporting the tape cassette, a tape loading block movably mounted on the chassis for drawing the tape from the tape cassette and holding the tape against the rotary head, and a head cleaning mechanism including a rotatable cleaning roller mounted on the chassis for movement into and out of contact with the rotary head. The rotatable cleaning roller comprises a rotatable shaft and a plurality of flaps fixed radially to the rotatable shaft. Each of the flaps comprises a flexible lapping tape coated with an abrasive material. The head cleaning mechanism also has a swing arm assembly angularly movably mounted on the chassis for moving the cleaning roller into contact with the rotary head to clean the rotary head in response to operation of the tape loading block.
