Abstract: System for recording/writing on a recording medium in which there are distributed, on the tracks, groups (G0) of tracks with positive continuous components and groups (G1) of tracks with negative continuous components. In reading, the values of the different signals are integrated for each track. Then, on the one hand, a first addition circuit S1 adds up the results of integration of the first tracks of each group of tracks and, secondly, a second addition circuit S2 adds up the results of integration of the last tracks of each group of tracks. A comparison circuit (CD) compares the results of additions of the two addition circuits to correct the track-following operation.

Abstract: A method and system for preventing cross-talk during reproduction of data recorded on a high density recording medium. The method includes the steps of receiving signals from at least three consecutively parallel information tracks on a recording medium, determining first and second cross-talk coefficients representing a degree of cross-talk between the three parallel information tracks, filtering the first and second cross-talk coefficients, correcting the cross-talk between the first, second, and third information tracks in accordance with the first and second cross-talk coefficients, forming a difference between the first and second cross-talk coefficients and integrating this difference to generate a track following correction signal, and repeating the above steps for each of the information tracks on the recording medium.

Abstract: In a magnetic storage system including a data conversion unit for performing reading or writing of data from or to a magnetic tape medium, and a system control unit, the data conversion unit has a plurality of electromagnetic transducers which are arranged so as not to overlap with one another in a travel direction of each of a plurality of recording tracks provided on the magnetic tape medium, and performs the reproduction of the data from each reproducing track using one of the electromagnetic transducers a plurality of which are assigned every recording track. In the system control unit, an error included in the regenerative data is detected. When an error is detected, the one electromagnetic transducer which performed the reproduction when detecting an error of the data is switched to another electromagnetic transducer assigned every recording track, thereby to perform the reproduction properly.

Abstract: A preferred embodiment of an electromagnetically controlled scanning magnetic transducer is described having two confronting core poles defining a physical transducing gap therebetween. A control winding is associated with each core pole. A control current applied to each control winding selectively saturates a portion of each core pole facing a record medium. Each saturated face portion defines an adjacent unsaturated highly permeable face portion. The highly permeable face portions of each core pole overlap across the gap to define a transducing zone. The information signal and control windings are arranged relative to one another to obtain information signal and control flux paths extending perpendicular to one another.

Abstract: A transducer for writing data on a magnetic carrier includes a magnetic circuit having a writing pole piece (PPI.sub.2), realized in thin magnetic layers of anisotropic magnetic material. A conductor (CMPI) for controlling the writing is coupled magnetically with the pole piece and acts upon the pole piece for writing a datum by reversing the magnetization. A second control is magnetically coupled with the pole piece (PPI.sub.2), but does not act upon the pole piece except in the case of non-writing by diminishing the effective action of the conductor control.
