  • Patent number: 7110328
    Abstract: An information recording/reproducing apparatus for recording and reproducing information to and from a magneto-optical storage medium that includes a first magnetic layer for recording at least information, a second magnetic layer for regulating a switched connective force, and a third magnetic layer for shifting a magnetic wall of recorded markings for information reproduction. The three layers being stacked on a transparent substrate to make up the storage medium. The information recording/reproducing apparatus includes an optical head and a magnetic head. The optical head has a light source and an objective lens, the light source is configured to emit at least a laser beam with a wavelength of about 780 nm, the objective lens having a numerical aperture of about 0.45 and is configured to focus the laser beam from the light source into a beam spot for emission onto the magneto-optical storage medium. The magnetic head is for applying a recording magnetic field to the magneto-optical storage medium.

  • Patent number: 7065023
    Abstract: A device and a method for judging the radial moving direction of light spots formed on the signal recording surface of an optical disc having grooves of two types, which are different from each other in terms of depth and which are arranged along a recording track that is a land of the optical disc. The judging section of the device judges the moving direction of the main spot on the basis of binarized data of a difference signal of the main spot and binarized data of a difference signal of one of spots on the side. With this arrangement, the moving direction of the light spots relative to a radial direction of the optical disc can be determined only by using difference signals without using any sum signal.

  • Publication number: 20050238325
    Abstract: A copyright management system that manages the time limits of the reproduction of a plurality of pieces of content in a batch manner. A content reproduction apparatus has a storage unit storing a reproduction permission ID list and the valid period information of each group ID and a reproduction control block for controlling the reproduction of content data attached with the group ID. The reproduction control block reads the group ID from content data and, if the read group ID is contained in the reproduction permission ID list and the current time is not in excess of the valid period of this group ID, permits the reproduction of the content data; if the read group ID is not contained in the reproduction permission ID list or the current time is in excess of the valid period of this group ID, the reproduction control block restricts the reproduction of the content data.
