    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： 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 end surface portion 8a of a gear housing 8, which is located on a motor unit 2 side of the gear housing 8, is opposed to the motor unit 2 and laterally extends. A brush holder 10 includes a plate portion 13 that is opposed to the end surface portion 8a. A case 15, which receives the control circuit board 14, is formed separately from the plate portion 13. A receiving through hole, through which the circuit board receiver 15 is receivable, is formed in the plate portion 13. The case 15 is constructed to be positionable next to the yoke 5 in a state where the case 15 is received through the receiving through hole. The yoke 5, the gear housing 8, the brush holder 10, the control circuit board 14 and the case 15 are assembleable in a direction parallel to an axial direction of the motor unit 2. The control circuit board 14 projects from the gear housing 8 on the motor unit 2 side, and a projected part of the control circuit board 14, which projects from the gear housing 8 on the motor unit 2 side, is received in the case 15. In this way, in the motor that integrally includes the motor unit, the speed reducing unit and the control circuit board, the gear housing of the speed reducing unit can be made compact, and the assembly work can be simplified.

    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.
