  • Patent number: 5251086
    Abstract: A tape drive with a tape head subassembly that can remotely adjust the position of the head. The drive has a baseplate that holds the cassette in place relative to the tape head. The head is operatively connected to a housing that is mounted to the baseplate by two adjustment screws. The housing also has a pivot member that allows the housing to pivot about the baseplate. The screws are located relative to the head, so that turning one of the screws rotates the housing and head such that it is parallel with the playing surface of the tape. Turning the other screw rotates the housing, such that the head is perpendicular with the length of the tape. A spring is attached to the baseplate and housing to hold the position of the head during adjustment. The spring, head and screws are positioned in a parallelogram so that adjustment of one of the screws rotates the head in only one plane.
