摘要： An optical recording medium for accurately deriving the address information or the disc rotation control information despite narrow track pitch and for recording signals to a high density, and a method and apparatus for recording and/or reproducing such optical recording medium. The optical recording medium has a wobbled groove and pits formed at a pre-set interval in an area between turns of the wobbled groove. The recording/reproducing method includes controlling rotation of the optical recording medium by a wobbled signal from the groove and detecting the position on the optical recording medium of a recording signal by pit signals detected from the pits. The recording/reproducing apparatus includes a detection device for detecting the wobbled signal from the groove and a detection device for detecting pit signals from the pits. The rotation of the optical recording medium is controlled by the wobbled signals detected from the groove and the position on the optical recording medium of the recording signal is detected by the pit signal detected from the pits.

摘要： A mark irradiation unit (130) irradiates an object with a mark. An image capture unit (140) captures an image of the object, and generates image data. Then, an image capture area data generation unit recognizes a position of the mark in the object, and cuts out image capture area data which is apart of the image data on the basis of the mark. For this reason, the mark irradiation unit (130) irradiates the object with the mark, and thus even when a positioning symbol is not printed on the object to be stored as the image data, only a necessary portion in the image data is cut out.

摘要： An information recording device can record a plurality of pieces of recording information, for instance, at different times, in an information recording medium provided by stacking first and second recording layers. A writing control element controls a writing element so that each piece of the information can be written over the first recording layer to the second recording layer. Furthermore, a boundary control member controls the writing element so that first boundary information is written in a recording area which is to be a boundary between the pieces of information in the first recording layer, and that second boundary information is written or ensured, in a recording area of a second recording layer which overlaps the recording area wherein the first boundary information of the first recording layer is written, as a recording area to be a boundary between the pieces of information in the second recording layer.

摘要： When a medium selection button 101 is operated, an optical disc reproduction apparatus 1 recognizes which medium is selected according to inputted medium selection information, and then opens a tray 104. Next, when a medium selection button 101 is operated, the optical disc reproduction apparatus 1 determines the inputted medium selection information and closes the tray 104. Next, the optical disc reproduction apparatus 1 acquires a priority list 16 and modifies the priority list 16 such that the order of the selected medium in the priority list 16 is a first priority and the remaining orders of the other media are successively lowered. The optical disc reproduction apparatus 1 performs a medium check for each of the media in accordance with the orders of the modified priority list 16.
