摘要： A flexible disc drive having a standard head for accessing standard tracks spaced specified intervals is provided with an additional head having a gap whose width smaller than the interval of the standard tracks so as to access the parts between standard tracks as additional tracks. Mutual interference is prevented by setting the recording carrier frequency for the additional head higher than that for the standard head. The capacity can be increased while maintaining the compatibility with a standard drive.

摘要： A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly pivotally attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information representative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly includes an arm and a head gimbal assembly. The head gimbal assembly includes a suspension. The arm has a length from the point where it pivots to the end of the arm. The arm and suspension can be thought of as having a fixed length for a certain sized disk drive. The length of the arm is greater than 4.0 times the lenght of the suspension. The ratio of the length of the arm to the length of the suspension is in the range of 4.0 to 20.0. The arm is made of a material with a stiffness-to-mass ratio in the range of 6.0 to 20.0 x 10 m. The resulting actuator arm is long and stable and the suspension is short so that the signal processing preamplifier chip attached to the arm near the end carrying the transducer is 8 mm or less from the head transducer. The material of the arm conducts heat away from the chip by moving it from the preamplifier chip to the surface of the arm in the airstream between the disk and the arm. The suspension includes signal-carrying wires which electrically connect the transducer to the preamplifier chip which have a length in the range of 4mm to 12mm.

摘要： A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly (134) moves the transducer (136) to selected areas of the disk where information representative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The first embodiment of the actuator assembly also includes an arm which has a first layer of material including a plurality of elongated fibers orientated in a first direction, and a second layer of material including a plurality of elongated fibers orientated in a second direction. The first and second layers are part of a composite material. The second embodiment of the actuator assembly also includes an arm made of a ceramic material. The transducer (136) is attached to said arm. The resulting actuator arm is long and stable. A preamplifier chip (600) is attached to the arm (134) near the end carrying the transducer (136). The material of the arm (134) is able to conduct heat away from the arm by moving it from the preamplifier chip (600) to the surface of the arm in the airstream between the disk and the arm. The arm may also include signal-carrying wires (600) which are positioned between the layers of the composite arm and heat conductive fibers to remove heat from a heat producing source, such as from a chip on the arm.

摘要： An enhanced-performance floppy diskette subsystem (70), which operates many times faster than a conventional floppy diskette subsystem (10), includes both an enhanced-performance floppy diskette drive (22'') and floppy diskette drive controller (12''). The diskette drive (22'') rotates a floppy diskette two or more times faster than that of a conventional floppy diskette drive (12), and includes two read/write ("R/W") channels (52a'' and 52b''). The controller (12'') includes a DRAM cache (72) that maintains an image of the data recorded on a floppy diskette (34). Two floppy controller channels (24a'' and 24b'') respectively interface between the cache (72) and the R/W channels (52a'' and 52b''). Both heads (42'') of the diskette drive (22'') concurrently record data from the cache (72) onto a floppy diskette (34), or reproduce data therefrom for storage into the cache (72). To a computer program executed by a host microprocessor, the floppy diskette system (70'') mimics the operation of a conventional floppy diskette subsystem (10).
