    摘要： In a magnetic disk apparatus, a head positioning signal is written on a magnetic disk, the written positioning signal is read out, the read positioning signal is demodulated to produce a position signal, and a data write/read head is positioned to a predetermined track in responses to the produced position signal. A head positioning signal is written into write tracks adjacent to each other along a radial direction of the magnetic head, the positioning signal is read out by tracing a read track bridging the write tracks, and a positioning error of the head positioning signal is generated from a shift of the read positioning signal with respect to the read track. Furthermore, the position signal is over-written by actuating the write head in the radial direction according to the positioning error.

    摘要： A magnetic disk apparatus has a rail support which supports guide rails for guiding a carriage on which heads are mounted. The rail support is positioned outside a magnet of a voice coil motor and mounted on a frame. The guide rails are disposed so as to extend across a cavity in the rail support and have their opposite end portions attached to the rail support. The guide rails do not vibrate even if the voice coil motor receives a reaction during head seeking, whereby the head positioning accuracy can be improved and the storage capacity can be increased. The rigidity of the guide rails is increased by supporting the opposite ends of the guide rails. This structure and a coaxial arrangement of a motor coil allow the overall length of the carriage and, hence, the overall size of the apparatus to be reduced.

    摘要： A magnetic disk storage system in which magnetic disk drives can be cooled effectively, and even if a blast device for one of he magnetic disk drives fall into trouble or cease operation, a temperature rise of this magnetic disk drive can be suppressed to the minimum. For this purpose, in the magnetic disk storage system containing a plurality of magnetic disk drives, blase devices ae provided for each of the disk drives, and the disk drives are separated by partitions in which openings are formed so that the cooling air can be passed between adjacent magnetic disk drives. With this structure, even if a blast device for a certain magnetic disk drive is out of order or stopped, a part of the cooling air from a blase device for the adjacent disk drives flows into the magnetic disk drive in question through the openings formed in the partitions, and consequently, the temperature rise of the magnetic disk drive whose blase device ceases operation can be suppressed to the minimum, to thereby enhance the reliability of the magnetic disk storage system.
