Abstract
When a lower head (34b) mounted on a lower head arm (32b) is in a standby position permitting no access to a magnetic recording disk (13), the lower head arm (32b) is housed in an opening (37) formed in a frame plate (3). Thus, the lower head arm (32b) and another (upper) head arm (32a) may maintain a predetermined distance even in a card-type magnetic recording device of small thickness. An electromagnetic shield material is adhered to the opening to protect the heads 34 (34a, 34b).
Claims11
A card-type magnetic recording device comprising;
- a disk housing space for housing a disk-shaped recording medium;
- a head arm carrying a magnetic recording/reproducing head and causing the magnetic recording/reproducing head to move between a recording/reproducing position to obtain access to the disk-shaped recording medium loaded in said disk housing space and a standby position at a distance from the disk-shaped recording medium;
- a frame plate which mounts said head arm and a disk drive device for driving the disk-shaped recording medium loaded in said disk housing space, on one surface thereof;
- and
- a circuit substrate, located on the other surface of said frame plate in overlap arrangement, having a plurality of elements arranged on the surface opposite to the surface facing said frame plate;
- wherein said frame plate has an opening or a concave part allowing the magnetic recording/reproducing head placed in said standby position and/or a part of the head arm to be housed therein, allowing the magnetic recording/reproducing head to move between the standby position and the recording/reproducing position without interference with said frame plate.
