摘要： A disk drive information storage device having a pair of disks for storing information, the storage device including a clamp for mounting disks on a hub, the clamp including an annular element having a first set of fingers extending from the annular element in the first direction parallel to the central axis of the annular element, the first set of fingers providing a radial force on the inside edge of one of the disks, and the clamp including a second set of fingers extending from the annular element in a second direction parallel to the central axis of the annular element and opposite to the first direction, the fingers of the second set being for imposing a radially force on an inside edge of a second disk. In another embodiment, a disk drive information storage device with a pair of disks includes a spindle motor having a rotor which includes a disk-shaped portion having an outer diameter, and an upper surface for supporting one of the pair of disks. A second one of the pair of disks is connected to the rotor on a side of the first disk opposite the spindle motor. A clamp having an outer diameter smaller than the outer diameter of the disk-shaped portion of the rotor is connected to a cylindrical portion of the rotor between the first and second disk. An actuator is provided to support first and second read/write heads, with the actuator being movable to position the first and second read/write heads such that the first read/write head reads information from or writes information to a portion of a second surface of the first disk between the outer diameter of the disk-shaped portion of the rotor and the outside diameter of the clamp. In one embodiment, the disk drive information storage device comprises a housing having a footprint that includes a first dimension of about 35 mm. In another embodiment, at least one of the disks of the pair of disks in the disk drive information storage device has a diameter in the range of from about 33 mm to about 34 mm.

摘要： High density magnetic disk storage and semiconductor module technologies are combined to provide a disk drive using a standard multilayer ceramic substrate as the disk drive base support member to support spindle and actuator assemblies including 1 inch diameter disks. The ceramic substrate has components and very large scale integration (VLSI) chips mounted directly thereon to avoid use of one level of packaging and presents standard pins to mount the drive using standard sockets to afford economy and reliability.

摘要： A disk/file for magnetic recording having overall dimensions of one quarter inch thick by about the size of a standard credit card with pin connectors for connecting into a receptacle such as for pc boards. The file features a rotor mounted on the rims of two disk and a stator external to and coplanar with the disks. An actuator features a "wobble" disk rolling around the inside of a nest of electromagnets and turning a small increment with each excursion around the nest thereby turning the shaft of the head support to actuate the head from track to track. The head support arm includes two sections hinged together and engaged with a third link that orients the head to eliminate head skew. A magnet withdraws the head devices from the disk surface to avoid sticktion when the disks are stationary. The head devices feature thin film cores that are oriented flat to the surface of the disk.

摘要： A data transducer head mounting structure for a height compacted, low power head and disk assembly of a fixed disk data storage subsystem has an elongated load beam including a head arm attachment end region for attachment to an outward end of an acuator head arm; a leaf spring loading region; a flexure attachment region for attachment of a gimbal flexure for mounting a transducer head; a dynamic loading tab formed at the outermost part of the head end region beyond the transducer head; and, a load beam region located between the leaf spring loading region and the dynamic loading tab. In one aspect of the invention a loading ramp structure is positioned adjacent to a peripheral edge of the storage disk and cooperates with the dynamic loading tab. In one independent aspect of the present invention, the load beam region includes two L-shaped flanges facing toward an adjacent data storage surface, and a trussing structure is attached to the outer surfaces of the flanges to enclose the load beam region. In a further aspect, the leaf spring loading region including two parallel outer segments defining a central longitudinal opening which are dimensioned to tune torsional mode resonances while maintaining a predetermined head loading bias force.

摘要： An erasable optical disk drive system is disclosed which utilizes an electron trapping media coated on the disk surface to store data in the form of light energy. Data is written onto the disk, which is contained in a light-tight contamination-free environment similar to a Winchester hard disk drive system, using a near infrared light laser beam. Data is read from the disk using a visible light laser beam. The entire optical disk drive system is designed to fit within a standard mini or 51/4 inch disk drive form factor for personal computers.

摘要： Formatting disk drive data using format field elements (FFEs). A processing module (which can be a general purpose processor or a RISC (Reduced Instruction Set Computer) processor) is employed to generate FFEs that are employed to govern operation of the various data formatting modules within a formatting system within a HDD. The determination of when a data formatting module stops operating in accordance with a first FFE and begins operating in accordance with a second FFE can be a predetermined period of time, a number of operations being performed, the meeting of some condition, or some other means. Each FFE can be viewed as being a multi-dimensional instruction that not only includes a configuration for a data formatting module, but also includes the conditions by which the configuration is to be governed by a subsequent FFE, among other things.

摘要： A data transfer system using cassettes with a tape drive is configured with a number of removable cassettes stored in front to rear alignment adjacent one side (e.g. the bottom) of the tape drive. Cassettes in a removable cassette tray in a magazine are disposed in two levels, and shifted between entry and exit regions of the cassette tray after each successive cassette is derived from the tape drive and a new one is supplied. A transporter moves the individual cassette between the cassette tray and the tape drive. Advantageously, this system is configured to fit into the form factor of a standard height enclosure, with a high density DAT format tape drive occupying the upper half and the cassette tray and magazine occupying the lower half.

摘要： The disk drive system includes an actuator, responsive to an adjustment value, for adjusting the position of a data head with respect to data tracks located on the surface of a disk, and a controller coupled to the data head and to the actuator. The controller receives servo information read from the surface of the disk by the data head. In turn, the controller determines an adjustment value to be applied to the actuator. The adjustment value is calculated dependent on a predetermined variable gain factor. Where the controller determines the position of the heat is oscillating about the center line of a predetermined data track at a frequenc above a predetermined frequency, the controller reduces the gain factor applied in determining the adjustment value.
