Abstract: Input data is modulated, a two-valued signal regarding a signal of a specific frequency is generated, and a logical arithmetic operation between the modulation data and the two-valued signal is executed. In accordance with the result of the logical arithmetic operation, the specific frequency component in the modulation data is detected. The modulating operation is controlled in accordance with the detection result. As mentioned above, the specific frequency component in the modulation data is detected by the logical arithmetic operation between the modulation data and the two-valued signal. By controlling the modulator on the basis of the detection result, the specific frequency component in the modulation data can be detected by a simple construction. For example, an amount of specific frequency component in the modulation data can be adjusted.

Abstract: A memory storage module for storing and accessing information which includes a flat storage medium having an X-axis and a Y-axis. A plurality of read/write heads are coupled to a head array assembly which is capable of motion along the X-axis. The head array assembly positions the heads adjacent to the medium. An X-axis motor is coupled to the head array assembly and causes the heads to undergo reciprocating substantially linear motion along the X-axis of the medium. A Y-axis motor creates linear motion between the heads and the medium along the Y-axis of the medium. The heads are controlled to store or access information on the medium as the heads move across the X-axis of the medium. The Y-axis motor moves the heads from track to track along the Y-axis of the medium. The Y-axis motor can be connected to move either the medium or the head array assembly along the Y-axis.

Abstract: A method and position control for a servo system for positioning a head laterally with respect to defined servo tracks. The servo system comprises a servo sensor and detector for sensing lateral position of the head and a compound actuator having a fine actuator portion and a coarse actuator portion. The position control provides position indications for the coarse actuator portion, which may comprise a table relating predetermined nominal lateral position indications to the defined servo tracks. The position control positions the coarse actuator portion at an estimated position with respect to the defined servo tracks, and responds to the servo sensor to determine which servo track is closest to the estimated position. The position control sets the coarse actuator portion position indication to the predetermined nominal lateral position indication of the closest defined servo track, e.g., by looking it up in the table. This thereby corrects the indication of the position of the coarse actuator portion.

Abstract: A recording apparatus includes a thin film magnetic head (20) with eight write units (21-28) positioned adjacent to each other in a transversal direction (y) to write data in parallel tracks on a magnetic tape (10). Switching arrangement 70 has a switch (SW) to switch from a normal mode to a combination mode. In the normal mode the switch is in a first position (D1) and the switching arrangement (70) couple a first data signal (S1) to a first write unit (21), a second data signal (S2) to a second write unit (22) etc., so that in the normal mode eight tracks (T21-T28) are written on the tape resulting in a first track density. In the combination mode the switch is in a second position (D2) and the switching arrangement couples the first data signal (S1) to the first and second write units (21 and 22), the second data signal (S2) to the third and fourth write units (23 and 24) etc. Hence, in the combination mode, four tracks (T1-T4) are written on the tape resulting in a second track density which is half the first track density. This second track density corresonds to the density of the write units of a magnetic head (2) of an apparatus (not shown) of an older generation.

Abstract: An improved servo system having an optical head array integrated into the magnetic head, and optical servo tracks incorporated on the magnetic side of a medium. The optical head array includes a light source array that individually illuminates the optical servo tracks through a beam splitter array and a lens array. Light beams incident on the optical servo tracks are individually reflected back through the lens array and beam splitter array to respective bi-cell photo detectors. The signals from the bi-cell photo detector are amplified by respective differential amplifiers to produce error signals indicative of the alignment of the magnetic head with the optical servo tracks. The error signals are combined by a circuit to produce a position error signal.

Abstract: There is provided a reproducing apparatus arranged to reproduce an information signal from a recording medium on which a number of recording tracks are formed in parallel with each other and the information signal is recorded on the recording tracks together with track number information indicative of numbers of the respective tracks, a pilot signal component being multiplexed onto the information signal periodically at intervals of a predetermined number of tracks. When the information signal is to be reproduced from the recording medium, the reproducing apparatus executes tracking control of the reproducing head with respect to a target track, by using the pilot signal component contained in a signal reproduced by a reproducing head. The reproducing apparatus determines the target track according to the track number information separated from the signal reproduced by the reproducing head. According to the above-described arrangement, it is possible to execute correct tracking control quickly after the start of reproduction. In addition, since the track number information recorded on the recording medium in a multiplexed manner is effectively utilized, it is not necessary to provide a special circuit for determining the target track.

Abstract: A fine lateral head positioner for a tape drive includes a frame mounted to a base of a tape transport. A tape head slides laterally along a head guide. A guide beam actuated by a fine position actuator applies limited transverse adjustments to the tape head relative to a tape transport path via a cam and cam-follower arrangement. A coarse positioner between the frame and the base provides coarse position adjustment of the tape head laterally among multiple sets of parallel tracks defined along a longitudinal direction of a magnetic tape moving along the tape transport path, and the guide beam provides fine position adjustment of the tape head enabling it to follow in real time a particular set of parallel tracks of the tape during each data writing or reading operation.
