摘要： An optical information apparatus of the present invention includes: an optical pick-up head including: a light source; a diffraction unit; a condensing unit; a beam splitter; a photodetector; and a tracking error signal generator. An optical recording medium has tracks arranged substantially at a constant pitch. An average of a pitch is tp. When a main beam is placed on the track, a first sub-beam and a second sub-beam are placed between the tracks. The tracking error signal generator performs a differential arithmetic operation with respect to signals output from a light-receiving portion receiving the main beam to generate a first push-pull signal, performs a differential arithmetic operation with respect to signals output from the light-receiving portions receiving the first sub-beam and the second sub-beam to generate a second push-pull signal, and performs a differential arithmetic operation with respect to the first push-pull signal and the second push-pull signal to generate a tracking error signal, in a case where an amplitude of the first push-pull signal obtained at the pitch tp is fluctuated when the light beam is scanned in a direction orthogonal to the tracks of the optical recording medium.

摘要： An optical pickup includes a hologram element divided into four regions in a direction parallel to a tracking direction of an optical information recording medium and a direction perpendicular thereto. The hologram element allows two pairs of diffracted lights from two paired regions adjacent in parallel with the tracking direction to be made incident into light receiving elements so as to align in the direction perpendicular to the tracking direction.

摘要： There is provided a program reservation recording device capable of reducing load on a server and performing program recording as is reserved by a user. Immediately before the reserved program is started and immediately before the end of it (S1), the program reservation recording device makes a request to an information providing server connected via a general-purpose network so as to acquire the latest program list (S2). The program reservation recording device compares the reservation information indicating the program reservation contents (start time, end time, etc.) to be stored in a memory with the latest program list acquired (S3). If any mismatch is present, the reservation information is updated according to the program list (S4).

摘要： An information recording medium is provided that includes a recording portion (3), which is irradiated with a recording light or a reproducing light so that information is recorded or reproduced thereto or therefrom. The recording portion (3) contains a first phosphor and a photon-mode photosensitive material. The first phosphor has a property of absorbing a first light having a wavelength of λ1/n and then emitting a second light having a wavelength longer than that of the first light, where λ1 is a wavelength of the recording light. The photosensitive material absorbs the second light and then exhibits a change in an optical constant thereof. A n-photon absorption sensitivity of the first phosphor with respect to the recording light is greater than a n-photon absorption sensitivity of the photosensitive material with respect to the recording light, where n is an integer not less than 2.
