Abstract: PROBLEM TO BE SOLVED: To provide an optical storage medium and an optical information device for recording and reproducing information with high reliability even in a case of using an optical storage medium whose jitter relating to the shortest mark and space is inferior to jitter relating to a mark and space which is longer than the shortest mark and space.SOLUTION: The optical information device includes: an optical pickup head for irradiating an optical storage medium with a light beam, and for receiving the light beam reflected from the optical storage medium, and for outputting a signal based on the received rays of light; a jitter measurement part for measuring the jitter of a signal to be output from the optical pickup head; and a determination part for determining whether or not the optical storage medium is non-defective or defective from the measured jitter. The jitter measurement part is configured to measure the jitter about a mark or space string which is 3T or more with respect to the optical storage medium in which digital information is recorded as a mark or space string which is kT long on the basis of an integer k which is 2 or more and a cycle T.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk medium which records a larger amount of user data in the optical disk with the same sizes by reducing a redundant capacity used for data other than actual user data such as a header or an accessory of the optical disk medium. SOLUTION: The optical disk medium comprises a track groove along which main information is recorded. The track groove is divided into a plurality of blocks. The plurality of blocks include a plurality of frames. Each of the plurality of frames includes one shape of wobbles indicating sub information among a plurality of prescribed shapes of wobbles. The plurality of blocks have address information. The address information is represented by at least one piece of sub information represented by shapes of wobbles of at least one of the plurality of frames. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a recording method for surely detecting a boundary between an unrecorded area and a recorded area when optimum power is determined by trial recording prior to recording of user data in a write-once type disk. SOLUTION: In a trial reading area of an optical disk, a light spot moves in a direction from the inner periphery to the outer periphery of the optical disk, and when the trial recording area is used from the outer peripheral side (a sector having a x mark is a recorded sector), the optimum recording power determined by trial recording in sectors 302, 303, 304, and 305 is used to perform recording in the sector 301. Thus, when next time trial recording is performed, the possibility of erroneously recognizing the recorded sectors as a unrecorded sector can be reduced. COPYRIGHT: (C)2009,JPO&INPIT
