Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: This method and apparatus for eliminating apparent offset in the servo code adjacent to a guard band on a magnetic memory disc utilizes at least two phases of servo code per magnetic cell for seeking and track centering, or track following, operations and two phases of guard band code per magnetic cell. The two phases of guard band code are each either in phase or similarly out of phase with the respective phases of the servo code in individual magnetic cells. Phase lacking on a selected phase of guard band code is achieved by providing a synchronizing code in the guard band using an irregular pattern of guard band code, providing a timing signal count representing a cell count, for example, decoding the synchronizing code to provide an end of code signal and utilizing the end of code signal and a predetermined cell count signal to achieve phase locking on the correct phase of the guard band code.
