摘要： Recording information is disclosed in which an information recording medium is irradiated with a recording energy beam that is power-modulated into at least a record power level and a record-ready power level lower than the record power level. The information is recorded on the recording medium in the form of length and interval of a mark portion. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion.

摘要： An optical disc apparatus in which processing time is shortened and processing accuracy is ensured upon focus offset processing for plural recording layers. Regarding each of mutually adjacent recording layers, based on a signal based on reflected light from a guide groove formed in a recording surface of the recording layer, a focus offset for an optical system with respect to the guide groove is learned, and based on the learned focus offsets for the respective recording layers, a focus offset for recording or reproduction is calculated and set. In an optical disc having three or more recording layers, a focus offset when the difference between the focus offset and the learned focus offsets for the respective recording layers is a value corresponding to the characteristic of the optical system is set as a focus offset for the respective recording layers or a common focus offset to the respective recording layers. Otherwise, a mean value of the focus offsets when the differences between the focus offsets and the learned focus offsets for the respective recording layers are values corresponding to the characteristic of the optical system is set as a focus offset for one recording layer.

摘要： An optical disc apparatus in which, regarding mutually adjacent recording layers, a focus offset of an optical system to a guide groove formed in a recording surface of the recording layer is learned based on a signal based on reflected light from the guide groove, and a focus offset for recording or reproduction is calculated and set based on the learned focus offsets for the respective recording layers. As the focus offset of the optical system for recording or reproduction, a mean value of the learned focus offsets for the respective recording layers is set as a focus offset common to the both recording layers. Otherwise, a focus offset when a difference between the focus offset and the learned focus offsets for the respective recording layers is a value corresponding to a characteristic of the optical system is set. This structure reduces processing time and ensures processing precision upon focus offset processing for plural recording layers.

摘要： An optical disc apparatus, as a learning operation before a recording or reproducing operation, rotates an optical disc at a first speed to read PID information, discriminates between lands and grooves of the optical disc, detects switching positions between lands and grooves, sets a rotation angle position of tracking pull-in of an objective lens of a time length that allows the PID information to be stably read, with respect to the switching position, and stores the set position information of tracking pull-in as learning result information. During recording or reproducing, the optical disc apparatus rotates the optical disk at a second speed higher than the first speed, pulls in the objective lens for tracking based on the stored position information of tracking pull-in, reads PID information, and performs the recording or reproducing operation while discriminating between lands and grooves and detecting switching positions between lands and grooves.

摘要： Random data is recorded on a higher-level recording layer and then, an optimum recording power is determined on a lower-level recording layer corresponding to the higher-level recording layer. Accordingly, it is necessary to record random data in more areas on the higher-level recording layer than areas for determining the optimum recording power on the lower-level recording layer. Consequently, there is a problem that the areas for determining the optimum recording power are excessively wasted. In the case of determining a recording condition for the lower-level recording layer corresponding to the recorded area on the higher-level recording layer, the recording condition for the lower-level recording layer corresponding to the recorded area on the higher-level recording layer can be easily determined by correcting the recording power using the change in transmittance that is obtained by comparing the case in which the data is recorded on the higher-level recording layer, with the case in which no data is recorded on the higher-level recording layer.
摘要翻译：随机数据被记录在较高级记录层上，然后在对应于较高级记录层的较低级记录层上确定最佳记录功率。因此，需要在较高级记录层上的更多区域中记录与在下层记录层上确定最佳记录功率的区域相比的区域的随机数据。因此，存在用于确定最佳记录功率的区域过度浪费的问题。在确定与较高级别记录层上的记录区域相对应的下层记录层的记录条件的情况下，对应于较高级别记录层上的记录区域的下层记录层的记录条件可以通过使用通过比较在高级记录层上记录数据的情况获得的透射率的变化与在高级记录上没有记录数据的情况来校正记录功率来容易地确定层。
