    Abstract: PROBLEM TO BE SOLVED: To achieve write strategy adjustment with front/rear space length considered while suppressing an increase in the consumption and processing load of a test area.SOLUTION: A moving amount WFMn in each start end edge position and a moving amount WRMn of each termination edge position are acquired such that an evaluation value dF in each start end edge position and an evaluation value dR in each termination edge position respectively approach predetermined reference values about each start end edge position classified by front space length of a mark and each termination edge position classified by rear space length of the mark. A deviation in each start end mark edge position and each termination mark edge position classified by the front/rear space length is reduced so that jitter can be reduced.

    Abstract: PROBLEM TO BE SOLVED: To improve reliability and operation performance regarding a recording operation to a multilayer recording medium.SOLUTION: To a most front layer of a recording medium when seen from a laser light incident surface side of the recording medium, a fixed management information track that records management information to be fixedly arranged in a data structure conforming to the UDF is set. The fixed management information track closes immediately after the setting. A writing request of management information is performed to the closed fixed management information track. In this case, management information relating to the writing request is recorded in one of other tracks by alternation processing. Accordingly, the management information is recorded at a position convenient for system operation by using the alternation processing.

    Abstract: With a large capacity of an optical disk and high-speed recording, a frequency of a recording signal is increased and a pulse width is narrowed. In the case that a laser is driven by a signal having the short pulse width, unfortunately the high-speed recording is hardly performed to an optical disk when a rise time and a fall time of the optical pulse are lengthened. During user data recording, a bottom driving current is set to a second bottom driving current value that is a current value of a threshold or less, so that the rise time and the fall time of the optical pulse can be shortened to perform the high-speed recording of the optical disk.
