G11B 7/24 (2006.01) Recording or reproducing by optical means, e.g. recording using a thermal beam of optical radiation, reproducing using an optical beam at lower power - Record carriers characterised by the selection of the material or by the structure or form

G11B 7/007 (2006.01) Recording or reproducing by optical means, e.g. recording using a thermal beam of optical radiation, reproducing using an optical beam at lower power - Arrangement of the information on the record carrier, e.g. form of tracks

G11B 20/14 (2006.01) Signal processing not specific to the method of recording or reproducing - using self-clocking codes

G11B 27/19 (2006.01) Editing - by using information detectable on the record carrier

G11B 7/00 (2006.01) Recording or reproducing by optical means, e.g. recording using a thermal beam of optical radiation, reproducing using an optical beam at lower power

G11B 7/09 (2006.01) Recording or reproducing by optical means, e.g. recording using a thermal beam of optical radiation, reproducing using an optical beam at lower power - with provision for moving the light beam or focus plane for the purpose of maintaining alignment of the light beam relative to the record carrier during transducing operation, e.g. to compensate for surface irregularities of the latter or for track following
