摘要： A condition of a recording pulse comprising a top pulse and a following pulse is determined in a predetermined order. In some embodiments, an mT pulse condition is first determined by test recordings with various power and pulse conditions, involving an inspection of recording quality; then an m′T/(n−m)T ratio is determined by test recording under the mT pulse condition fixed; and finally an nT pulse is configured based on the ratio. A phase shift can be corrected by test recording with the nT pulse.

摘要： The present invention enables a recording condition closer to an optimum to be obtained even for media unknown to a drive. The present invention provides a method that is especially effective for the case where it is applied to a code identification scheme, such as PRML in which code identification is performed on the basis of information on the amplitude of an RF signal. A condition for a recording pulse comprised of a top pulse, an intermediate pulse and a last pulse is configured in a predetermined order, that is, a reference condition is first determined by a test recording involving an examination of recording quality and changes in conditions for a power and a pulse width, then a condition for the last pulse is determined by a test recording using the reference condition, and subsequently a condition for the intermediate pulse is determined using the reference condition and the last pulse. A phase shift is corrected by a test recording using the recording pulse obtained by configuring the above conditions.

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： An optical information recording apparatus is suitable for detection of deviation between a strategy and a record pattern. Test record is performed on an optical recordable medium using a predetermined strategy. A binarization signal that is obtained by reproducing the test record result is counted. A pit length and a land length included in the binarization signal are specified using a histogram of the count result. A plurality of the reproduction patterns is searched and extracted from a record area based at least in part on the pit length and the land length. Deviation between a strategy and a record pattern formed by the test record is detected through comparison of the obtained reproduction patterns through the search.
