Claims

[Claims for Utility Model Registration] (1) A device for converting information signals using a magnetic disk cartridge consisting of a flexible magnetic disk and an enclosure thereof, comprising: a rotation mechanism for the disk; and a rotation mechanism for the disk; a first magnetic head that contacts one main surface of the disk to convert information signals; and a second magnetic head that contacts the other main surface of the disk and converts information signals at a position opposite to the first magnetic head. a first spring support sheet that supports the first magnetic head; a second spring support sheet that supports the second magnetic head; and the first and second magnetic heads. a carriage for guiding the magnetic head in the radial direction of the disk; supporting the first elastic support sheet so as to support the first magnetic head via the first elastic support sheet; a first arm swingably attached to the carriage; and supporting the second spring support sheet so as to support the second magnetic head via the second spring support sheet. a second arm swingably attached to the carriage; and a first biasing force that applies a biasing force to the first arm in a direction to bring the first magnetic head into contact with the disk. means for applying a biasing force to the second arm in a direction to bring the second magnetic head into contact with the disk; and applying the biasing force of the second biasing means to the second arm. conversely, means for selectively moving the second magnetic head to a position away from the disk; and means for allowing the first magnetic head to come into contact with the disk; 1. A magnetic disk drive device comprising: a rotational position limiting means for the first arm provided to limit the first arm from protruding more than necessary in the direction of the second magnetic head. (2) The magnetic disk drive device according to item 1 of the utility model registration claim, wherein the first and second resilient support sheets are gimbal spring sheets.
