摘要： A voice coil actuator return path and a slotted flex circuit member for a linear actuator (70) of a disk drive (110). The outer return path (72) is formed from laminations of low carbon steel and supports and positions a central guide track (53) on which a carriage assembly (50) slides. The outer return path (72) is oriented in a rectangle that is coupled to a disk drive and includes an aperture (78) through which a portion of the carriage assembly passes. A flex circuit member (10), which electrically connects the read/write heads (52A and 52B), includes a slot (25) that enables the central guide track (53) to pass through, thereby enabling connection to the carriage assembly near a central axis (40) of the carriage (50). The flex circuit member (10) has a center of mass and center of force approximately equally distributed on each side of a vertical plane passing through a centerline of the central guide track.

摘要： A magnetic tape head actuator assembly has a stepper motor having a threaded shaft (50) wherein a bracket supports the tape head assembly. A threaded split nut (85) is positioned between bores of the bracket and rigidly attached to the bracket whereby the bracket is moved back and forth along the shaft (50). The split nut (85) has an annular groove (95) encircling its outer perimeter so as to position a circular spring (100) therein for providing an inwardly directed compressive force on the split nut (85). A shock suppression sleeve (105) is spring biased by spring (102) to engage the split nut (85) over a distance of the split nut (85). In the event of a mechanical shock, a ramped interior portion of the sleeve (105) provides a reactionary force on the split nut (85) for resisting the expansion thereof, thereby substantially eliminating split nut backlash.

摘要： The invention relates to a process for adjusting the access arm of a disk operating system, the access arm of which carries at least one transducer which generates a position signal (43) from continuously read positional data. In order to position the transducer on the corresponding track, a servo drive (36) is actuated. The position signal (43) is scanned with a constant scanning frequency (fa) and converted to digital values which are fed to a controller that operates digitally and at a constant operating frequency (fr). Voltage pulses of constant pulse frequency (fp), whose polarity and/or duration (tp) are adjusted in function of the output signal of the controller (48), are fed to a drive coil. The respective ratios of the pulse frequency (fp), the scanning frequency (8a) and the operating frequency (fr) are whole numbers. The process can be used to reduce electric losses in the servo drive (36) and to prevent fluctuations in the control system.

摘要： A system and method for controlling the movement of a member, particularly the heads of a disk file, to a specified position in a predetermined path, makes use of an electromagnetic actuator responsive to control signals and of position reference information and a transducing means for reading such information to produce a position signal. The position signal is sampled regularly and, together with the actuator control signal, used to update a velocity estimator. During the deceleration phase of the movement, a new actuator control signal is generated at each sample time from the square of the estimated velocity divided by the computed distance-to-go to the specified position.

摘要： A disk drive system for a PC includes a rotatable magnetic storage disk (10) and a read/write arm (12) having a reading/writing head (14). During manufacture, servo control tracks are written onto the surface of the disk (10) by means of an external servo writing system including a control arm (40) independently pivotable by means of a motor/encoder unit (50). The control arm has a null sensor (80) which detects the relative displacement of the read/write arm (12) and control arm (40). The control arm (40) has a relatively high inertial mass, whereas the read/write arm has a low inertial mass. Servo control tracks are written by moving the control arm (40) continuously across the surface of the disk. Servo control card (70) receives output signals from the encoder (50) and null sensor (80), and instructs the hard disk control electronics (30) to move the read/write arm (12) into register with the control arm (40) at the instant the control arm (40) lies in register with a region of the disk on which it is desired to write a servo control track (because the read/write arm (12) has a low inertial mass it is moved much more rapidly than the control arm (40)). The read/write arm (12) is then maintained in its position relative to the disk (the servo control card using the output of the null sensor for this purpose), and a servo control track is written. The control arm (40) continues to traverse the disk during writing of the track, and when the track has been written the read/write arm (12) is once again moved rapidly into register with the control arm (40) at the location at which the next servo control track is to be written.

摘要： A system for positioning a transducing head of a disc drive over a selected track (42) of a rotatable disc (40) includes an actuator assembly (20, 50) having an E-block body (25) including a cavity (37), at least one actuator arm (30) extending from the E-block body (25), a head suspension mechanism (34, 36, 38) including the transducing head connected to an end of the actuator arm (30), and a pivot cartridge (26) in the cavity (37) in the E-block body (25). The E-block body (25) is attached to the pivot cartridge (26) and forms a hinge point (39) between the E-block body (25) and the pivot cartridge (26). A low resolution motor (22) rotates the actuator assembly (20, 50) about an axis (24) to effect coarse positioning of the head with respect to the selected track (42) of the rotatable disc (40). A piezoelectric element (27, 52) in the E-block body (25) is selectively expanded and contracted to distort the E-block body (25) around the hinge point (39) to effect fine positioning of the head with respect to the selected track (42) of the rotatable disc (40).
