摘要： A reference track (38) is recorded in a longitudinal direction on a recording medium. During recording of an information signal along parallel tracks (150) on the medium a deviation of the reference track in a transverse direction from its nominal position with respect to the medium transport is detected by one or more sensor heads (51a, 51b) mounted in a fixed relationship with respect to the medium transport. A positionably mounted data head (143) is moved in transverse direction in accordance with the sense and magnitude of the detected deviation, thereby maintaining the data head in a known geometric relationship with the reference track during the recording process. During playback the same reference track may be utilized to follow the thusly recorded parallel tracks.

摘要： @ A flexible disc drive carriage slide assembly (52) is described which allow a transducer head supporting carriage (57) to move relative to the disc drive mainframe (50). The carriage slide assembly comprises a movable member (56) mounted to the carriage and a fixed member (54) mounted to the mainframe. A plurality of roller bearings (122) are retained within the slide assembly between the movable and fixed members in a manner to allow the movable member to move relative to the fixed member while providing a tight coupling therebetween. The slide assembly is designed such that its orientation with respect to the carriage element can be varied, orientation selection being determined by space and the disc drive manufacturing considerations. The fixed member may be formed as part of the mainframe to further reduce system costs.

摘要： System for obtaining read/write head (26) positioning movement and control for a storage disc drive. The rotational energy source for the disc (10) is also utilized for the additional task of indexing the read/ write head assembly (26, 28). To provide a simple, low-cost and reliable means of controlling the position of head assembly (26, 28), a belt (18), driven by the disc drive, drives rollers (50, 52) in opposite directions, and solenoid actuating means (68, 70) are employed to engage one of rollers (50, 52) with a track position wheel (80) to cause said wheel (80) to rotate in one of two opposite directions. The rotational movement is converted (44, 46, 47, 49) into indexing movement of the read/write head assembly (26, 28).

摘要： A method and device for storing and accessing information on a flat storage medium (116) having X and Y axes. A read/write head (120a) is positioned adjacent to the medium and an X-axis motor (108-109) creates a reciprocating substantially linear motion between the head and the medium along the X-axis of the medium. A Y-axis motor (112) creates a linear motion between the head and the medium along the Y-axis of the medium. The head causes information to be stored or accessed on the medium as the head moves across the X-axis of the medium. The relative substantially linear motion of the head along the Y-axis moves the head from track to track along the medium. The relative motion between the head and the medium can be created by moving either the head or the medium.
