摘要： An optical disc having a plurality of information tracks, each information track having a servo field including a pair of wobbled pits and a clock pit. The distance between one of the wobbled pits and the clock pit in each servo field is selected such that the optical disc includes at least three different types of servo field. These differnt types of servo field appear in a predetermined sequence for every one or more contiguous information tracks. A driving apparatus for driving such an optical disc has a direction detecting circuit for detecting the moving velocity of a movable portion of an optical head, and a speed detecting circuit for detecting the relative velocity of the movable portion.

摘要： By avoiding the problem that in a hybrid optical disc, an optical pickup suitable for a standard-density recording area cannot operate as desired in a high-density recording area, damage to the disc drive or optical disc is prevented and optimal control is enabled. Access operation identification information such as reproducing identification information indicating whether or not information recorded in the user data area of the optical disc can be reproduced under the reproducing conditions of the optical disc driving apparatus is recorded in the lead-in area. The optical disc driving apparatus reads this type of access operation identification information, compares it with access operation identification information possessed by the optical disc driving apparatus, and if they do not correspond, does not carry out access operations by the optical head to the user data area, because reproducing or recording compatibility with the optical disc is lacking.

摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.

摘要： An image processing device is provided that corrects image data obtained by sequentially reading out as a current, charges from unit regions from a radiographic image detector provided with signal lines extending along a predetermined direction. The correction includes estimating the respective leakage current superimposed on the read-out current when the charge is read out from a target unit region using a leakage current estimation equation, formed from a single exponential function or from a sum of plural exponential functions, for respective leakage currents of unit regions that are positioned along the same signal line as that of the target unit region and whose charges are in an unread state when the charge is being read out from the target unit region, and correcting the image data corresponding to the target unit region on the basis of the leakage current estimate result.
