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.

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.

An information recording medium comprising a substrate (1), a recording layer (2) formed on the substrate in order to record information, a color filter (4) formed on the substrate, and a thermal reflectance variation layer (3) formed on the substrate in order to vary light reflectance by heat incident to irradiation of light and to reflect visible light entering from one side of the substrate through a color filter. High precision color writing or color label writing can be carried out on an information recording medium such as DVD and BD where a label can be written on the surface by irradiating light.

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.

Provided herein is an optical disc having: an optical plotting layer 17 which is formed at a label surface B-side and on which an image is formed by heat change with a laser beam 28 emitted from a recording surface A-side; a protective layer 18 which is formed at the label surface B-side of the optical plotting layer 17, protects the optical plotting layer 17, and through which the image can be viewed from the label surface B-side; a substrate 15 which supports the protective layer 18 and the optical plotting layer 17; and a guide track 24 which is formed on the optical plotting layer 17 so as to be intermittent in a guide direction.
摘要:
Content data (11), handling limit data (12), and a check program (13) are provided in a data group (10) recorded on an information recording medium (1). The check program (13) causes a reproducing device to read the content data so as to make the reproducing device function as a check device for checking the data state of the handling limit data. Thus, when the handling limit data (12) is tampered, the check program (13) is executed by the reproducing device to find the tamper.
