Abstract: An apparatus for positioning the sets of read/write heads of an information storage disk that is a completely sealed unit with its own connecting cable (16) and mounting apparatus (28). The apparatus includes a carrier connected through a slot (46) in the sidewall of a tubular stator (2) to a cylindrical armature (24). The carrier is driven axially along the outside of the stator as the armature moves axially inside the stator to position set of read/write heads that may be attached to the carrier in their desired position with respect to an information storage disk. The armature is connected to the carrier by pins (25 and 26). The surface of the carrier facing the stator has a concave contour to match the exterior surface of the stator and extends beyond the stator slot a sufficient amount to completely close the stator slot no matter what the axial position of the carrier. A projection extends from the concave surface of the carrier into the slot, and the lateral edges of the projection form bumpers for the carrier. The armature and carrier are slotted to provide easy accesss for armature wiring which extends through the carrier and connects to a cable connected to the carrier at a point spaced apart from the stator.

Abstract: A carriage assembly (1) for use in optical recording apparatus wherein the carriage body (8) to which the sensing means are attached is mounted to the assembly guide (rails 6, 7) through the combined center of mass (29) of the carriage body and sensing means so that upon activation, the apparatus is not subjected to bending or torsional stresses which cause the tangential and radial tracking errors. By placing the center of mass in the plane of the bearing support, the carriage body can be constructed of lighter weight materials thus allowing for more rapid and precise assembly movement.

Abstract: A method for adjusting the frequency response of a servo loop (28) is provided that positions a servo head (46) at a nominal position over a medium and determines the frequency response (80) of the servo loop (46). A compensation gain (79) is determined at the nominal position such that when the compensation gain (79) is combined with the servo loop's frequency response (80), the compensation gain (79) causes the frequency response (80) to approach a desired frequency response. In addition, a servo loop and a disc drive with such compensation gain are provided.

Abstract: A read-after-write head (100) for four channel azimuth recording in one mode of operation and two channel non-azimuth recording in another mode of operation. Four forward write head gaps (104, 106, 108, 110), four read head gaps (120, 122, 124, 126), and four backward write head gaps (112, 114, 116, 118) are geometrically positioned within a rotatable and laterally indexable face plate (102) of a recording head housing. The read and write head gaps collectively provide four forward write channels, four read channels, and four backward write channels. During the azimuth mode of operation, the head is rotated to the preselected positive or negative azimuth angle and all of the read and write channels are utilized. During the non-azimuth, or vertical, mode of operation, write channels two and four are used in combination with read channels one and three to provide two channel non-azimuth, or vertical, operation.

Abstract: A rotary actuator which carries magnetic read/write heads (14) into engagement with a magnetic recording medium has a rotor which includes an arm (16), a pivot assembly (18) and return path members (30, 32) extending from the pivot assembly (18). The stator includes a permanent magnet (26), a magnetic member (28) and magnetic coils (22, 24) on the magnetic member (28). When the magnetic coils (22, 24) are energized, flux flowing through the magnetic member (28) and the return path members (30, 32) aids or detracts from the magnetic flux generated by the permanent magnet (26).

Abstract: A bearing design for a rotatable assembly includes two freely rotating balls mounted on the axis of rotation of the assembly and axially separated, one near each axial end of the assembly. Each ball is confined by a moving concave (preferably conical or frustro-conical) bearing surface of the rotatable assembly and a corresponding fixed concave bearing surface of a mounting attached to a frame, housing, or similar non-rotating structure. One of the fixed mountings is preferably attached to a compressible spring to provide a controlled axial pre-load to the assembly. The balls are substantially enclosed and lubricant provided in the enclosed cavity. In the preferred embodiment, the rotatable assembly is a rotary actuator assembly of a disk drive. Compared to conventional ball bearing designs, the present design reduces the number of parts and volume of space occupied by the bearings, reduces hysteresis, and improves shock resistance.

Abstract: A disk drive including firmware for overcoming stiction and breaking free the heads of a disk drive which may adhere to the disk surface when the disk is at rest. Upon start-up of the disk drive, if stiction at the head/disk interface occurs, the voltage to the spindle motor and/or actuator motor may be rapidly fluctuated so as to cause a pulsing of the spindle motor and/or actuator motor. Pulsing both the spindle motor and actuator motor creates forces in a plurality of radial directions to allow the head(s) to break free from the disk(s) in the direction of least resistance. Moreover, as the resonant frequency of the spindle motor varies depending on the number of heads that are stuck, the firmware pulses over a range of frequencies including the various resonant frequencies of the spindle motor corresponding to various numbers of heads stuck.

Abstract: A track control method for a data cartridge tape drive which includes a multichannel head assembly, a positioner for controllably positioning the multichannel head assembly transversely to a transport path for a tape driven by the drive, and drive electronics responsive to a carrier servo signal. The track control method initializes the data cartridge tape drive by operating the positioner to move the head assembly to a preselected transverse position. Next, the tape is moved along the transport path and the positioner is moved to substantially minimize a feedback signal derived from the carrier servo signal. The head assembly is stepped a first predetermined number os steps in a first transverse direction until the carrier servo signal is not detected. If the carrier servo signal is not detected, then the positioner is stepped so as to move the head assembly a second predetermined number of steps in a second transverse direction to locate a reference track.
