摘要： 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.

摘要： A reader portion (150) of a magnetoresistive head is disclosed. The reader portion (150) includes a magnetoresistive read element (156) for reading information from a magnetic media (216) and a non-magnetic element (153) to detect and cancel thermal changes in the read head. A spacer (155) is positioned between the magnetoresistive read element (156) and the non-magnetic element (153). A plurality of electrical contacts (166, 167, 168) connect the magnetoresistive read element (156) and the non-magnetic element (153) to external circuitry.

摘要： A disk drive system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp assembly includes a set of ramps for loading and unloading the transducing elements to and from the disks in the disk stack. The ramp assembly is attached to the base. The ramp assembly has a series of fixed ramps which are either formed as one integral unit or formed of separate portions. The actuator assembly includes a set of arms. Attached to each arm is a suspension. Attached near the free end of each of the suspensions is a transducer. Also attached to the suspension is a load tang. The load tang rides over the surface of the ramp when the transducers are loaded to or unloaded from a disk surface. The load tang includes a plastically deformable portion which may be irreversibly deformed during assembly of the drive and more particularly, deformed when all of the heads are unloaded from the disk to the ramp assembly for the first time. The deformable portion would allow for z-height adjustment and attitude adjustment of the arm necessary to adjust for stack up tolerances of the various components of the disk drive. The load tang could be finely adjusted and properly mated with the ramp as installed in the disk drive. The deformable region of the load tang could be a formed feature in the body of the tang, or a plastically deformable material within the body of the load tang. Still another embodiment includes a thermoset polymer to be attached along a portion of the load tang. After plastic deformation and adjustment to allow the actuator arm to properly mate with the ramp structure, the thermoset polymer can be heated to allowed to cool while engaged to permanently set the adjustment between the load tangs and the ramps of the ramp assembly.

摘要： A slider body configuration, or slider, for carrying a data transducer in cooperative relationship with a rotating data storage disc. The slider includes a plurality of landing pads which serve to minimize the contact area between the slider and the discs when the heads are parked in contact with the discs, and the landing pads project from surfaces which are farther removed from the disc surface than the air bearing surfaces, thus minimizing the size and strength of any liquid miniscus formed between the slider and the disc when the slider and disc are in contact. By recessing the bases of the landing pads from the air bearing surfaces, the effect of the landing pads on the separation between the data transducer and the discs is minimized.

摘要： An air bearing slider for a disc drive has an overcoat localized on the air bearing surface to provide a continuous covering over a leading portion of the air bearing surface. The overcoat terminates in a trailing cut-off line, and a trailing portion of the air bearing surface is not covered by overcoat. The overcoat also covers the pole tips of the transducer at a pole tip recession from the air bearing surface. The leading portion covered by the overcoat includes all of the air bearing surface that contacts the disc during contact/start/stop, which is protected by a uniform continuous overcoat layer. The trailing cut-off line is disposed at an angle to expose the trailing corners of the air bearing surface, such that all of the overcoat is elevated above the lowermost portion of the air bearing surface through pitch and roll angles of flying at inner and outer radii. Methods of applying the localized overcoat include subtractive and additive photolithographic deposition processes. The overcoat over the pole tips protects the pole tips during subsequent processing steps of forming the slider cavity.
