G11B11/10543 - CPC Classification

Classification description:

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; Heads for reproducing using optical beam of radiation

Sub-classes:

G11B11/10545 » {interacting directly with the magnetisation on the record carrier} 12
G11B11/10547 » {interacting with the magnetisation of an intermediate transfer element, e.g. magnetic film, included in the head} 5
