G11B5/588 - CPC Classification

Classification description:

Recording by magnetisation or demagnetisation of a record carrier; Reproducing by magnetic means; Record carriers therefor; Disposition or mounting of heads relative to record carriers with provision for moving the head for the purpose of maintaining alignment of the head relative to the record carrier during transducing operation, e.g. to compensate for surface irregularities of the latter or for track following for track following on tapes by controlling the position of the rotating heads
