摘要： This invention relates to a magnetic head device and a disk drive, which are suitable for application to a mass-storage floppy disk drive. A first and second rails are provided on the disk side in projected form on a slider of each of magnetic head elements 20 so as to extend in a tangential direction R of a track of the disk and be parallel with each other. A head chip for recording and reproducing data in a state of being in contact with a recording surface of the disk and in a standard recording density is provided substantially in the central position of the first rail. Another head chip for recording and reproducing data in a state of being levitated from the recording surface of the disk and in a high recording density is provided in a position on the rear side of the second rail 26b with respect to the tangential direction R of the track. A width of the first rail of each magnetic head element is narrower than a width of the second rail thereof. The slider is inclined and levitated so that the second rail approaches the recording surface of the disk.

摘要： The present invention relates to a magnetic recording medium and a magnetic recording/reproducing apparatus for the same. In the magnetic recording medium there are provided a read/write region which permits modification of written data and a read-only region dedicated to the reading of data, which is used for reading only once writing is done. In recording servo information to a data format region of the magnetic recording medium, the time width of servo information in the read-only region is set shorter than that in the read/write region.

摘要： A magnetic head carriage device includes a carriage base on which a lower head is mounted, and an upper arm on which an upper head confronting the lower head is mounted, the upper arm having a width in a lateral direction and a base portion at which the upper arm is fixed to the carriage base, the upper arm being vertically movable to the carriage base around the base portion. A head load spring exerts a downward actuating force on the upper arm such that the upper arm is pressed toward the carriage base, the head load spring having an end portion at which the head load spring downwardly presses the upper arm and a base portion at which the head load spring is fixed to the carriage base. A spring guide mechanism restricts a movement of the end portion of the head load spring in the lateral direction such that the end portion is maintained in the center of the width of the upper arm.

摘要： An enhanced-performance floppy diskette subsystem, which operates many times faster than a conventional floppy diskette subsystem, includes both an enhanced-performance floppy diskette drive and floppy diskette drive controller. The diskette drive rotates a floppy diskette two or more times faster than that of a conventional floppy diskette drive, and includes two separate and independent read/write ("R/W") channels. To provide enhanced-performance, the floppy diskette drive controller includes a DRAM cache that maintains an image of the data recorded on a floppy diskette present in the floppy diskette drive. Two separate and independent floppy disk drive controller channels respectively interface between the cache memory and the R/W channels included in the enhanced-performance floppy diskette drive. Operating in this way, both heads of the enhanced-performance floppy diskette drive concurrently record data from the cache onto a floppy diskette, or reproduce data from a floppy diskette for storage into the cache. To a computer program executed by a host microprocessor, the enhanced-performance floppy diskette mimics the operation of a conventional floppy diskette subsystem.

摘要： A recording/reproducing device for use in a floppy disk apparatus. The device has a first coil and a second coil, both wound arond a common core. The coils are connected to each other at one end, and have taps, respectively. Both coils have characteristics optimized for data-reading. A read circuit is connected to the second ends of the coils. A write circuit is connected to the taps of the coils. The write circuit writes data on a recording medium by using that portion of the first coil which extends between the tap of the first coil and the connection point between the coils, and that portion of the second coil which extends between the tap of the second coil and the connection point between the coils.

摘要： A bead positioning apparatus includes a carriage for moving a magnetic head to a specified position of data tracks in a storage medium, a motor for driving the carriage depending on excitation pulses from a step motor, a light shielding plate mounted on the carriage, a light-emitting element, a light-sensitive element opposing to the light-emitting element through the light shielding plate and a position-judging device for judging the position of the magnetic head depending on the excitation pulses of the step motor and a signal of the light-sensitive element generated when light is shielded by the light-shielding plate, wherein the light-emitting element and the light-sensitive element are connected to a power source through a common switching element and the position-judging device outputs a signal, when the switching element is turned off, which is the same signal as if the light-sensitive element were device sensing light. The switching element being turned off represents a stand-by mode which is a power saving feature.
