Abstract: Systems and methods for improving loading and unloading of a read or write head onto and off of a disk medium. Particular embodiments may assist in loading a read or write head to, or unloading a read or write head from, a load location over a surface of a disk medium in such a manner that damage to the surface of the disk medium (e.g., load location) is either prevented or minimized. The prevention or reduction of damage may be achieved by ensuring that a read or write head has sufficient clearance over the surface of a disk medium as the read or write head moves over the surface (e.g., as the head moves parallel to the surface) during a head loading or unloading process.

Abstract: A head stack assembly comb (154) for maintaining the heads (44) of a head stack assembly (26) in spaced relation is disclosed. The head stack assembly comb (154) includes a comb body (158) and a latch (218). The comb body (158) engages an upper surface of an uppermost actuator arm (30a) in the head stack assembly (26). The latch (218) engages a lower surface of this same actuator arm (30a). When installing the comb (154), the comb (154) is pivoted relative to the head stack assembly (26). This brings the latch (218) into engagement with the noted actuator arm (30a) and causes the latch (218) to pivot in a first direction against a spring (214), and then in the opposite direction by the action of the spring (214) on the latch (218) to engage the latch (218) with the lower surface of the noted actuator arm (30a).

Abstract: A method for creating a hard drive includes installing a slider in a disk drive having at least one disk lubricated with a first stage lubricant. The slider is designed to be in contact with the disk at initial use. The slider is burnished. A second stage lubricant is added to the disk after the burnishing step. The first stage lubricant provides less lubrication than the second stage lubricant, allowing the slider to be burnished in a controllable manner during the burnishing step. The second stage lubricant then provides lubrication to the disk during use by the end consumer.

Abstract: Disclosed is a head stack load comb used in the controlled loading of a head of a head stack assembly (HSA) onto a disk during the assembly of a disk drive. The HSA includes an actuator arm, a head, and a loading surface. The load comb includes a base structure and at least one ramp finger projecting approximately perpendicularly from the base structure. In order to load the head in a controlled manner onto the disk, the loading surface of the HSA is rotated along the ramp finger until the head is in a load position and then the base structure is actuated in a vertical direction such that the ramp finger is correspondingly actuated in the vertical direction towards the disk until the head is loaded onto the disk.

Abstract: A disk drive system includes a base, a disk rotably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information reprexentative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also parks the transducer or unloads the transducer to a park position. A portion of the actuator assembly rides over a ramp to a park position. The ramp includes a mechanism for increasing the coefficient of friction on the surface of the ramp. The coefficient of friction on the surface of the ramp is increased to help retain the actuator in its parked position. This helps maintain the actuator assembly in a parked position in the event of shock loading from dropping a computer or a disk drive. This in turn helps prevent head crashes or failure of the disk drive and possible data loss.
