摘要： Apparatus for protecting a disc drive from damage due to non-operational mechanical shocks, the disc drive comprising a rotatable disc having an inner radius and an outer radius and a controllably rotatable actuator adjacent the disc. A snubber is provided adjacent the disc, the snubber having a body portion rigidly affixed with respect to the disc and snubber arms connected to the body portion. The snubber arms extend from the body portion towards the disc and above and below the elevation of the disc, with each snubber arm having a distal end located at a position adjacent the disc between the inner and the outer radii of the disc and towards the outer radius of the disc. The height of each snubber arm limits deflection of the disc at the outer radius of the disc as a result of mechanical shock forced supplied to the disc drive assembly.

摘要： A pulse qualification apparatus and method provides for qualifying signal pulses from a raw data signal by comparison to a variable qualification level. Pulse qualification is done on a read signal developed by moving a magnetic transducer relative to addressable portions of a magnetic disk. A qualification level generator circuit generates a qualification level signal which varies in value depending upon the addressed portion of the magnetic disk. A threshold detector is used in qualifying pulses from a transducer read signal by comparison to the qualification level signal to generate an encoded pulse signal representing occurrences of qualifying pulses.

摘要： A pulse qualification apparatus and method provides for qualifying signal pulses from a raw data signal by comparison to a variable qualification level. Pulse qualification is done on a read signal developed by moving a magnetic transducer relative to addressable portions of a magnetic disk. A qualification level generator circuit generates a qualification level signal which varies in value depending upon the addressed portion of the magnetic disk. A threshold detector is used in qualifying pulses from a transducer read signal by comparision to the qualification level signal to generate an encoded pulse signal representing occurrences of qualifying pulses. Error recovery is accomplished by increasing or decreasing the qualification level of the address portion of the magnetic disk where the error occurs. This process is repeated until qualifcation channel requirements are met. Using variable qualification for defect on a magnetic disk consists of running a manufacturing test process with qualification levels raised slightly from normal operation to detect defects which are caused by reduced amplitude. Likewise, operation with reduced qualification levels detects extra amplitude defects. The address locations of these defects are then mapped into memory.

摘要： In a medium having data fields and servo fields, a dual servo format includes a plurality of large and small servo fields for determining the position of a transducer over the medium. The large servo fields have a circumferential length that is larger than the circumferential length of the small servo fields. Both types of servo fields are distributed across the medium among the data fields.

摘要： A hard disk drive having a plurality of disks mounted on the rotor of a current limited, electronically commutated dc motor. Windings on the stator of the motor are divided into serially connected run and start sections and first and seconds drive circuits are provided to operate the motor by alternatively enabling the first drive circuit to pass currents serially through the two sections of the winding and enabling the second drive circuit to pass currents through only the run sections of the windings. During spin up of the disk drive to operating speed, the first drive circuit is enabled and the second drive circuit is disabled to drive the disks to the speed at which the back emf limits on the acceleration of the motor using both sections of the windings reduces the acceleration to the maximum acceleration achievable at the current limit using the run sections alone. Spin up is then completed by enabling the second drive circuit and disabling the first drive circuit.

摘要： A shock load detection device mounted on a disk drive housing of a computer disk drive unit to issue a write-fault signal should the disk drive unit have a mechanical shock imposed thereon. The detection device includes three piezo-electric crystals mounted orthogonally between a base and a seismic mass. Any shock load along x, y, and z axes through the piezo-electric crystals produces an electrical charge which is amplified, filtered, and compared for issuing a write-fault signal. The write-fault signal is used to stop the writing of read/write heads on a spindle of a head disk assembly before the shock imposed thereon could otherwise move the read/write heads off track causing a data error.
