摘要:
An optical recording method to record information with a mark length recording method, where an amorphous mark and a crystal space are recorded only in the groove of a substrate having a guide groove, with the temporal length of the mark and the space of nT (T denotes a reference clock period; n denotes a natural number). The space is formed at least by an erase pulse of power Pe; all the marks of 4T or longer are formed by a multi pulse alternatively irradiating a heating pulse of power Pw and a cooling pulse of power Pb while Pw>Pb; and the Pe and the Pw satisfy the following relations: 0.15≦Pe/Pw≦0.4, and 0.4≦τw/(τw+τb)≦0.8, where τw denotes the sum of the length of the heating pulses, and τb denotes the sum of the length of the cooling pulses.
摘要:
The present invention provides a recording method for a phase-change optical recording medium. The recording method of the present invention contains the step of irradiating an electromagnetic wave having a multipulse pattern so as to perform recording on a phase-change optical recording medium containing a phase-change recording layer. This method is characterised in that a starting time of a front pulse of the multipulse pattern delays 0.5T to 1.25T from a starting point of the first reference clock relative to the recording mark, where T is a reference clock of the multipulse pattern.
