Recording on or reproducing from the same record carrier wherein for these two operations the methods are covered by different main groups of groups - or by different subgroups of group ; Record carriers therefor using recording by magnetic means or other means for magnetisation or demagnetisation of a record carrier, e.g. light induced spin magnetisation; Demagnetisation by thermal or stress means in the presence or not of an orienting magnetic field using a beam of light or a magnetic field for recording and a beam of light for reproducing, e.g. light-induced thermomagnetic recording, Kerr effect reproducing characterised by the transducing operation to be executed; Overwriting or erasing; Direct overwriting, i.e. performing erasing and recording using the same transducing means using a single light spot
