A film supporting plate made of a plastic is formed with a window into which a head holder made of a metallic thin plate is inserted. The head holder has an opening for baring a magnetic head, and holds a head base on which the magnetic head is mounted. An adhesive is applied so as to extend from a peripheral face of the head base to a rear face of the head holder. When the adhesive is hardened, the head base adheres to the head holder and is fixed relative to the film supporting plate. A thickness of the head holder is thin in comparison with that of the film supporting plate. The head holder is fitted into a front portion of the window of the film supporting plate so that the head base enters the window. A protrusion amount of the head base toward the back side is reduced by an amount of the head base entering the window.

A data storage device comprises: a data member comprising means for storing data on a surface thereof; and a data retrieval member. The data retrieval member comprises: a plurality of heads for reading data from the data member; and a plurality of storage buffers each arranged to store data read from one of more of said heads. The retrieval member is arranged so as to output the contents of a plurality of said storage buffers sequentially. This allows fast and efficient reading of the data stored. Also disclosed is a telecommunications switch which may employ such a storage device. The switch dynamically assigns data packets to nodes as an output path becomes available to minimise queuing delays.

A disk apparatus, e.g., a magnetic disk apparatus has a storage medium in the form of a disk which is rotated and accessed, and is designed so as to reduce the occurrence of scratches on the storage medium due to contact between the head and the storage medium while ensuring stable access to the disk-type storage medium. In addition to a main dowel which is provided on a suspension and which supports a magnetic head at a center of the same, an auxiliary dowel is provided on the suspension on the air outflow side relative to the main dowel to limit the tilt of the magnetic head at the time of loading.

The invention discloses a magnetic sensitivity detection device of a thin-film induction magnetic head, which comprises a fixed isolation mechanism, a magnetichead clamping mechanism and a displacement detection mechanism, wherein the magnetic head clamping mechanism and the displacement detection mechanism are both fixedly installed in the fixed isolation mechanism. During detection, a sound equipment power supply is turned on to generate sound such that a magnetic head fixed to a clamping piece vibrates under the impact of sound waves, thereby simulating and reproducing the vibration state of the magnetic head of a tape recorder in operation, and the displacement of the magnetic head is monitored by a laser displacement sensor mounted at the same height as the magnetic head. Further, theinvention further discloses an implementation method of the magnetic sensitivity detection device of the thin-film induction magnetic head. The clamping piece and the laser displacement sensor at thetwo ends of a connecting rod can move at the same time only by pulling up or down the connecting rod without separately adjusting the clamping piece and the laser displacement sensor to the scale lines at the same height, thereby realizing the effect of simultaneous adjustment, lower errors, and more convenience.
