摘要： The type of a disc is determined by detecting focus error signals and the amount of returned light while emitting light with a wavelength such as infrared light which maximizes the focal length and moving an objective lens in the direction of an optical axis. If the S shape and AS immediately after the surface are greater than those at the surface, the optical disc is determined to be an optical disc with a largest capacity. It is determined whether or not there is a reflective layer at a depth equal to or less than 0.1 mm. If there is no reflective layer thereat, it is determined whether or not there is a reflective layer at a depth of 0.6 mm. If there is a reflective layer thereat, the type of the reflective layer is determined based on TE and RF signals with blue light. If the blue light is not adaptable to the layer, red light is emitted, and replay of the recording layer at a depth of 0.6 mm is performed.

摘要： A data transfer system transfers original data from a first data storage device to a second data storage device. The transfer system includes a compressor, an encryptor, and a controller. The compressor receives the original data from the first data storage device, generates compressed data of a smaller size, and passes the compressed data to the second data storage device. The encryptor makes a predetermined cryptographic key and passes the key to the second data storage device. The encryptor also receives the original data from the first data storage device, encrypts the original data with the cryptographic key and then sends the encrypted data back to the first data storage device. The controller controls the compressor and the encryptor and gives the first data storage device a first erase instruction, telling the first data storage device to erase the original data, in accordance with a first transfer command.

摘要： It is an object of the present invention to record to and reproduce different types of optical disks using light beams with different wavelengths. In an optical head device for recording to and reproducing high-density optical disks using an objective lens with a large NA, a sawtooth-shaped hologram is used for recording to and reproducing conventional optical disks such as DVDs. For blue light, a sawtooth height is the light path length 2λ, and second-order diffraction light is used. Red light generates first-order diffraction. The hologram is blazed and has convex lens function, and corrects chromatic aberration of the refractive lens. A relay lens is disposed between an infrared laser light source and the objective lens, and the light beam that is emitted from the infrared laser light source is substantially converged by the relay lens, and then, as it diverges once again, it is incident on the objective lens, which focuses the light beam into a spot on the recording surface of an optical disk after passing through an approximately 1.2 mm substrate.
