摘要： A positioner apparatus for moving a transducer head (14) from one to another of a number of parallel tracks extending lengthwise along a recording tape (100), including a rotary cam (16) with surfaces (116, 216) defining an inclined plane, a cam follower (20, 22, 24) for riding upon such surfaces, a transducer carrier or mount (12) coupled to the cam .follower, and guides (28, 30) along which the head carrier is moved by the cam and follower and which serve to index the transducer head at a number of mutually spaced but generally parallel positions extending transversely across the width of the recording tape. Preferably, the rotary cam comprises a wheel-like member having an annular recess (50) around its outermost periphery, with the edges of such recess defining a pair of complementary, spaced, curved ramp surfaces whose path of curvature is concentric with that of the wheel-like member itself. The cam follower preferably comprises a series of laterally spaced rollers which fit into the said cam recess and ride upon the ramp surfaces, such rollers being mounted upon pins or shafts (20', 22', 24') coupled to a slide or block (26) which in turn is coupled to the transducer mount (12), certain such roller pins being mounted in fixed position to establish a reference, and at least one other being laterally movable to accurately follow the cam surface.

摘要： A recording member for digital data, particularly a recording tape (10), has a plurality of generally parallel, closely-spaced recording tracks (I-VII) which each contain pre-recorded track-identifying and transducer-positioning servo information, as well as defined data-recording areas (18). The pre-recorded track-identifying information (32, 34) preferably comprises a digitally-encoded individual track address, and the servo information (36, 38) comprises separate bursts used in centring the transducer upon a particular track Preferably, each such track has a dedicated area (14, 16) at its beginning, end, or both, which contains continuous repetitions of such positioning information, there being no data areas in such dedicated portions. Digital encoding of track addresses utilizes binary-type code format, accomplished by defining a binary "zero" as a recorded burst present at a first number of sampling points, and defining a binary "one" as a burst present at a second number of sampling points of a second duration. The pre-recorded positioning information includes certain non-recorded "gaps" (x) which serve as initializing signals, and the preferred system for utilizing the pre-recorded, servo- controlled record member utilizes peak-detection and minimum-threshold techniques to accurately distinguish unrecorded gaps from noise, or the like, on the one hand, and to distinguish coded signal bursts from other possible recorded signals, or noise, on the other hand. The preferred system is entirely self-clocking, i.e., the record member does not carry a recorded clock track, and thus does not require the additional transducer required where recorded clock tracks are used; at the same time, the area on the record member otherwise occupied by the clock track is available for data-recording usage.

摘要： A disc recorder includes a main support frame (12) and a cover (14) sealed to the frame to define an enclosure (29). A disc drive (108,112) mounted to the frame rotates a disc hub (118) to which a hard disc media (20) is secured. Disc read/write heads (24) are positioned by an arm (26) and an arm drive (28) supported by the main frame. A main filter plenum (90) is secured to the frame which defines inlet (52) and outlet (56) apertures. A filter (92) is disposed within the plenum. An impeller on the underside of the disc hub includes a plurality of vanes (134). A cross ambient filter (160) communicates the enclosure with atmosphere for balancing the pressure within the enclosure with atmospheric pressure. A self-contained, modular cartridge recorder (18) is secured to the support frame.

摘要： A head arm (25) includes a pick-up head (18) at one end (22) and a pivot (24) for mounting the arm to a base (12) at a pivot position remote from the one end and spaced from an opposite end (28) with a drive (26) coupled to the arm in the area between the pivot and the opposite end for pivoting the arm to position the pick-up head with respect to a data disk (15). Preferably, the drive is a linear motor having a stator coil (70) embedded in the pick-up arm and field producing magnets (71, 73, 76, 78) mounted to the base. Preferably, also, there is a velocity pick-up coil (72) positioned to detect arm movement and provide, in connection with signals applied to the linear motor, synthesized linear velocity control signals employed for the controlling of the arm position. The arm preferably comprises upper (30) and lower (32) apertured members connected along their outer edges (31) by bridge members (35).

摘要： A method for positioning and maintaining a disc head (20) over a desired track centreline on a disc (14) rotatably carried on a disc drive (10). The distance between the current position of the disc head and the desired track centreline is monitored, and a signal generally proportional to that distance is applied to the disc head moving mechanism to cause the disc head to move toward the track centreline. The control signal is clipped if it exceeds predetermined maximum and minimum values.

摘要： Analog servo-positioning signals transduced from a recorded member (10), such as embedded servo signals (28, 30; 32, 34) recorded on a disc memory or the like, which are to be compared to one another in order to derive an error signal indicative of off-track position deviations, are normalized for accurate responsive positioning changes by use of an analog-to-digital converter (62) reference by both a positive and a negative summation of the two analog signals and supplied with the individual analog signals as inputs, such that the digitalized output comprises a pair of digital signals, the first representative of the quotient of the first analog signal divided by the summation of the two analog signals, and the second representative of the second analog signal divided by the same summation of analog signals. The two resulting digital signals are then processed in a microprocessor (68) by subtracting the second such quotient-representative signal from the first. thereby providing a fully-normalized digital signal representative of the deviation from true position. An analog multiplexer (66) is preferably used as a switching input to the A/D converter, and the latter comprises a multiplying type A/D converter.
