Meinders Erwin R, Langereis Gerardus R, Hellmig Joachim W: A recorder, a disc and a method for recording information on a disc. Koninklijke Philips Electronics, May 26, 2006: KR1020067002865

When recording information in tracks or in a two-dimensional pattern care must be taken not to irradiate the adjacent tracks or pits. This results in a loss of data density on the recording medium because of the track pitch or pit distance that must be observed. A reduction in track pitch is possibl ...

Martens Hubert C F, Meinders Erwin R: Additional data channel in between marks. Koninkl Philips Electronics, liu gong wang zhongzhong, February 8, 2006: CN200380107919

A device has a head for recording information by writing marks in a track on a record carrier via a beam of radiation. The radiation is controlled to write the marks (40) having a main mark intensity (44) and a mark length within a predefined range of mark lengths. Further secondary marks (41) are r ...
