摘要： PROBLEM TO BE SOLVED: To provide a disk player which can obtain optical magneto-optical signals with less wobble signal leakage even from a high-density magneto-optical disk.
SOLUTION: The change-over switch 503 selects the magneto-optical signals MO from the calculation unit 501 to output, when the disk type discriminator circuit finds that the disk currently played back is a magneto-optical disk of a large track pitch (a 1st generation MD or a high-density MD1). Alternatively, when the disk discriminator circuit finds that the currently played back disk is a narrow pitch magneto-optic disk (high-density MD3), the switch 503 selects the magneto-optical signals MO from the calculation unit 502 to output.

摘要： PROBLEM TO BE SOLVED: To appropriately execute the removal of the same phase in a wobble component of each double spiral track without bringing the request for enhancing the precision of an optical system.
SOLUTION: After different gains are given to each of a detection signal (I) of a 1st reflected light and a detection signal (J) of a 2nd reflected light with respect to a disk, on which a 1st track and 2nd track are double-spirally formed and one side of each track is physically wobbled, a data signal corresponding to a magnetic field pit train is obtained by the subtracting process between the detection signals of the 1st reflected light and the 2nd reflected light. Especially, the gain ratio is changed over according to the reproducing time of the 1st track and the reproducing time of the 2nd track.

摘要： PROBLEM TO BE SOLVED: To provide a reproduction device of a simplified configuration capable of reading data in a stable manner.
SOLUTION: A manual scanning method is adopted whereby a user holds a reproduction device and moves it on a hologram recording medium to read each element hologram without providing a scanning mechanism to the reproduction device. The reproduction device performs the operation of storing the data read out from each element hologram if it is not stored in the storage means. When a predetermined amount of data read out from the element hologram has been accumulated in the storage means, the reproduction data are rebuilt and generated. It is permitted that the order of reading each element hologram is not prescribed, and that the data read out from a certain element hologram is read out in duplicate. Proper reproduction can be made corresponding to the manual scanning.

摘要： PROBLEM TO BE SOLVED: To enhance the design of a recording medium itself in a hologram recording medium for recording computer data. SOLUTION: The optical recording medium as a hologram memory contains is used to record data in a first form such as computer data and data in a second form such as image data that can be recognized by a person on the optical recording medium. That is, the recording medium is used as a recording medium with a large capacity for computer data, as well as recording image data visually recognized by a person are recorded so as to make the image visible in the appearance of the medium. Since the recorded data in the first form are computer data which are premised as being read out by a reproducing apparatus, the reproducing apparatus reads out reproduced images of the recorded data in the first and second forms from the optical recording medium, and then extracts only the recorded data in the first form.
