摘要： Embodiments of the present invention pertain to a disk drive coupling apparatus for rigidly coupling a disk drive to a chassis of a computer. In one embodiment, the disk drive coupling apparatus includes a disk drive to chassis coupler and a disk drive to chassis coupler engaging mechanism. One end of the disk drive to chassis coupler can be coupled to the chassis of the computer. The disk drive to chassis coupler engaging mechanism is capable of causing the other end of the disk drive to chassis coupler to apply pressure to the disk drive, thus, the disk drive can be rigidly coupled to the chassis.

摘要： A control system for an actuator arm assembly of a hard disk drive reduces the Non-Repeatable Run-out (NRRO) caused from external sources exciting higher-frequency actuator arm assembly modes. The actuator arm assembly includes a primary actuator and a secondary actuator. The control system includes a primary control loop controlling the primary actuator and a secondary control loop controlling the secondary actuator. The secondary control loop includes at least one peak filter at a frequency corresponding to at least one frequency that is greater in frequency than the primary mode of the actuator arm assembly. The primary actuator can be any type of primary actuator. Similarly, the secondary actuator can be any type of actuator that is located between the primary actuator and a read/write head.

摘要： An active control mechanism and method for stabilizing a servo-controlled actuator system such as an actuator system in a data recording disk drive by compensating the vibrational modes of the actuator's arm assembly. The control mechanism has a sensing arrangement which can include one or more individual sensors attached to the actuator at locations where they generate signals in phase with the vibrational modes, and especially with all the major vibrational modes, of the arm assembly. A control mechanism derives from the signals an adjustment signal consisting of three corrective terms--a stiffening correction, an active damping correction and an inertia reduction correction--and the adjustment signal is used in the feedback control loop to stabilize the actuator system.

摘要： The present invention generally relates to fabricating a bond pad for electrically connecting a laser diode to a slider and a TAR head in a HDD. The bond pad is deposited on a surface of the head that is perpendicular to the air bearing surface (ABS). The head is diced and lapped to expose the bond pad on a top surface of the head and mounted on a slider. The laser diode and a sub-mount may be coupled to the top surface of the slider—i.e., the surface opposite the ABS—by connecting to the bond pads. Specifically, both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads. Conductive bonding material is used to bond the laser diode and the sub-mount to the bond pads.

摘要： The present invention generally relates to electrically connecting a laser diode to a slider and head assembly of a TAR head in a HDD. The laser diode is coupled to a sub-mount. The laser diode and the sub-mount are coupled to the top surface of the slider and/or the head assembly. Either the slider, the head assembly or both have bond pads exposed through their respective top surfaces to provide an electrical connection to both the laser diode and the sub-mount. Both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads and are in contact with the bond pads. Conductive bonding material is used to not only bond the laser diode and the sub-mount to the bond pads, but also to electrically connect the bond pads to the electrodes.

摘要： Approaches for inducing a magnetic bias in a magnetic recording disk. A biasing apparatus comprises a soft magnetic material member having a shape comprising two opposing recesses, denoted an upper recess and a lower recess. A first magnet is disposed within the upper recess and a second magnet disposed within the lower recess. An air gap exists between the first magnet and the second magnet. An opening in the soft magnetic material member is sized to accommodate at least a portion of the magnetic recording disk between the first magnet and the second magnet. The magnetic field produced by both the first magnetic and the second magnetic flows (a) in the same direction, and (b) perpendicular to the plane of the magnetic recording disk. Using this approach, magnetic material on the disk, such as magnetic islands of a bit pattern media, may be erased and polarized in the same direction.
