摘要： It is an object of the present invention to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly to provide a method especially effective when applied to code identification methods, such as PRML, wherein codes are identified based on amplitude information of an RF signal. In order to accomplish the object, an RF signal received from a photo-receiving part 108 of a pickup is converted into sampling data by an A/D converter 300, and a Viterbi decoder 302 performs code determination using the sampling data. Codes included in a reproduction signal are then determined by synchronizing recording pulses with the reproduction signal using the result of the code determination. Then, the result is used to specify a part to be detected in the codes, and finally an amplitude of the specified part is detected.

摘要： It is an object of certain inventive aspects to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly, to provide means for obtaining a preferable recording condition even for a high-speed recording in which conducting a test recording is difficult. In order to accomplish the object, a power and a phase of a recording pulse are simultaneously corrected at predetermined timing, depending on a recording speed or a recording position such as an inner or outer circumference. For instance, a phase shift ΔPhase generated due to a continuing recording from an inner circumference to an outer circumference at ×2 speed is corrected simultaneously with a correction of a power shift at the timing when a recording speed is changed from ×2 to ×4. For the other recording speed, in the same manner as above, a power and a phase shift are simultaneously corrected at every time when a recording speed is changed.

摘要： There is provided a method which can obtain an optimum recording condition even in case of a medium unknown to a drive, in particular, a recording condition effective for avoiding recording distortion in case of high-speed recording having a difficulty in test recording. An index representing recording quality, for example, a jitter, is acquired by test recording with power values or pulse widths gradually changed, and a recording condition where the change in jitter value is maximum is specified as a condition with recording distortion. For example, in case that the change in jitter value between the power values P1 and P2 shows a maximum change amount Δmax, recording distortion is generated with a power value equal to P1, P2 or more. Therefore, by applying the power value P1 to the upper limit of the recording condition, recording can be performed with no recording distortion.
