Abstract: This optical disc drive has an optical pickup head that emits a light beam to an optical storage medium, detects the light beam reflected from the optical storage medium, and outputs a signal based on the received reflected light; a jitter measuring unit for measuring jitter in signals output from the optical pickup head; and an evaluation unit for determining from the measured jitter if the optical storage medium is good or defective. The jitter measuring unit measures jitter in a train of 3T or longer marks or spaces from an optical storage medium to which digital information is recorded as a train of marks or spaces of length kT based on a period T and an integer k of two or more.

Abstract: Optimum movement of first and last signal pulses based on the data pattern is determined before data recording to record marks in the correct position. A specific pattern signal is read from a disc track and digitized with an appropriate slice level by the digitizing circuit (115). A pulse position offset measuring circuit (120) then measures specific edge intervals in the resulting digital signal. Movement of the first and last pulse by the pulse moving circuit (110) is then set so that the offset between the measured edge interval and a predetermined standard edge interval is ideally zero.

Abstract: A laminated structural body is manufactured by laminating unidirectionally arranged strands and a web such that two layers of the web sandwich the strands therebetween. A cylindrical web is delivered in a direction parallel to a central axis thereof. A polymer liquid is discharged from a spinning head, which is disposed in the cylindrical web and rotated about the central axis of the cylindrical web, toward an inner surface of the cylindrical web to spin strands of the discharged polymer liquid. The spun strands are arranged in a direction substantially parallel to the circumferential direction of the cylindrical web and laminated on the inner surface of the cylindrical web. The cylindrical web with the strands laminated thereon is folded flatwise to sandwich the strands between the two folded layers of the web.

Abstract: When data is reproduced by an apparatus which is different from an apparatus used for recording the data, the fluctuation of edge positions of the reproducing data increases, making reproduction incompatible, and the present invention solves this problem. The present invention comprises reproducing learning means 13 and 24 for switching a frequency characteristic of the reproducing system, which detects the changes of the local optical constant, to a predetermined frequency characteristic, and recording learning means 20 for correcting the start edge or end edge position of the recording pulse for each combination of length of a mark block and length of the preceding or subsequent space, so that the edge position of the binarized reproducing data comes to a desired position, and since the frequency characteristic of the reproducing system is unified before learning the edge shift amount caused by the thermal interference between marks, the length of the recorded marks and spaces can always be constant, which improves the reproducing compatibility among reproducing apparatuses.
