摘要： In an information recording system, information is recorded, through light from a light source, in a recording medium comprising a recording layer which has a phase reversibly changeable between a crystal phase and an amorphous phase. The light source emits, for forming a record mark in the recording layer, multi-pulse light which includes a head heating pulse, a head cooling pulse and following rear heating pulse and rear cooling pulse in the stated order. The head heating pulse includes a front division and a rear division. The difference in light-emission power between the head heating pulse and an immediately following cooling pulse is larger than the difference in light-emission power between another heating pulse and an immediately following cooling pulse.

摘要： An optical disc and associated recording/reproducing apparatus is described which creates and reads wobbled tracks on the optical disc. Wobbled tracks are formed in correspondence to a wobble signal which is phase modulated with address information. Phase modulation is used to convert the address information to the wobble signal. The carrier to noise ratio (C/N) of the address information is good, and it is possible to shorten the wobbling amplitude of the tracks while maintaining addressing capabilities. It is thus possible to arrange the track pitch in a high density, and increase the recording capacity of the optical disc.

摘要： A trial writing operation is performed on a phase-change optical disc using write and erase light-emitting powers, which together are varied according to predetermined variation ratios respectively. Signals relevant to said trial writing operation are reproduced from said disc. Optimum ones of the write and erase light-emitting powers are determined using the thus-reproduced signals. The predetermined variation ratios for the write and erase light-emitting powers may be the same as each other. Alternatively, the trial writing operation may be performed on a phase-change optical disc using write and erase light-emitting powers which are individually varied according to predetermined variation ratios respectively.

摘要： Optical information recording medium in which, information of a data format constructed by an ID section and a data section can be recorded and regenerated from both regions of a land portion and a groove portion formed on a disk face. Information such as an address is recorded to the ID section as a format by a PPM recording system when information is recorded to the data section by a PWM recording system. The information recording medium may have a land portion and a groove portion formed in a spiral or concentric shape. A land mark may be formed in a position information section of the land portion and constructed by a pit recorded as position information, and a groove mark may be formed in a position information section of the groove portion. The groove mark may be constructed using an interrupting portion between grooves and recorded as independent position information different from the position information of the land portion.

摘要： An optical disc having track grooves formed in a radial direction of the disc, and with the disc being divided into a plurality of zones, wherein track grooves are formatted into waved patterns, based on a predetermined modulation rule, in the radial direction of the disc to record zone address information for each of the divided zones. The waved pattern may overlap over recorded user data. Each zone has a recording capacity in which an arbitrary recording capacity is added to a data recording capacity needed for each divided zone.
