A magnetic storage system having an air bearing slider designed to minimize disk damage. The magnetic storage system may include a load/unload structure for loading or unloading the slider when the spindle motor is powered down. The air bearing slider includes an air bearing surface and at least one non-air bearing surface. For example, the non-air bearing surface may include a first etch surface and/or a second etch surface. The non-air bearing surface has at least one rounded corner. The non-air bearing surface may also have at least one rounded edge.

An apparatus and method for modifying a slider to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, an increased dynamic pitch of the slider is provided, the increased dynamic pitch increasing the height of a leading edge (LE) portion of the slider with respect to the disk and reducing the height of the TE portion of the slider with respect to the disk, wherein vertical motion of the TE portion does not collapse an air bearing provided by the LE of the slider flying above the disk.

An apparatus and method for modifying the air bearing force of the trailing edge of a slider to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, a shaped TE which minimizes the air bearing force at the TE portion of the slider, to minimize the normal load and friction during contact to reduce slider bounce.

A method for burnishing a slider in a disk drive in which the disk is rotated in the opposite or reverse direction from that used to develop the air-bearing and to read and write data is described. Rotating the disk in the reverse direction results in no air-bearing being formed and the slider being in contact with the disk surface. The burnishing removes material over the magnetic transducers in the slider which separate the transducers from the disk resulting in greater sensitivity. Optionally the stopping point for burnishing can be determined by monitoring measurable parameters such as the change in the MR resistance (MRR), i.e., ΔMRR/MRR until a selected range is achieved. The invention can be used to remove an overcoat from the air-bearing surface of the slider, remove protruding areas from the slider and to remove debris from the disk surface.

An apparatus and method for utilizing an off-center gimbal to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, an off-center gimbal device is coupled with the slider and the suspension away from the center of the slider and closer to the TE portion of the slider such that when the TE portion of the slider contacts a disk a bouncing motion of the TE with respect to the disk is reduced.

A method for controlling a burnish cycle to minimize cycle time is disclosed. MR sensor resistance measurements are used to monitor interference with the recording surface and when clearance is not detected, steps are taken to fine tune the interference signal.

A hard disk drive utilizes hard disks that recover the historically unused read/write space or real estate located in the load/unload zone. Approximately one-half of the load/unload zone is recovered and available for reading and writing operations by forming a first or radially outermost read/write track beginning immediately adjacent to the inner radial edge of the load/unload zone and proceeding radially inward from there to the conventional location of first tracks in the prior art. In another version of the invention, almost the entire load/unload zone is recovered and available for reading and writing operations by aligning the first track with the center of the load/unload zone and proceeding radially inward from there as described above. Both of these versions make significant additional surface area on the disk available where, in the prior art, no data was stored, thereby increasing the efficiency and storage capacity of the hard disk drive.
摘要:
A disk drive utilizes a slider that is designed to fly very high or well above the surface of the disk when loading onto the disk and until a reading or writing operation requires the head to go to a relatively low-flying position with respect to the disk. Thus, the slider has two or more altitudes at which it flies depending on the operating conditions of the disk drive. The different altitudes of the slider are achieved by adjusting three primary variables: the rotational speed of the disk, selecting the radial position of the slider/actuator arm, and by the gram load. Other factors that may be used to tune this performance include pitch static attitude, pitch stiffness, and air bearing surface design.
