摘要： An optical head device according to the present invention includes a splitting section for splitting a light beam having been reflected from an optical storage medium. The splitting section includes: a first main region transmitting a first interfering portion; a second main region transmitting a second interfering portion; and first and second sub-regions through which the first interfering portion is transmitted with a lower rate than in the first main region and through which the second interfering portion is transmitted with a lower rate than in the second main region. The splitting section splits the reflected light beam into: a first main light beam transmitted through the first main region; a second main light beam transmitted through the second main region; a first sub-light beam transmitted through the first sub-region; and a second sub-light beam transmitted through the second sub-region. The splitting section further includes a swapping section for swapping a portion of the first sub-light beam with a portion of the second sub-light beam.

摘要： An optical pickup head is provided with a light source, a diffracting means for creating a plurality of diffracted beams, a converging means for focusing the diffracted beams onto an optical storage medium, a beam branching means for branching the plurality of beams reflected by the optical storage medium, and an optical detecting means for outputting a signal corresponding to the amount of light of the received beams. The optical detecting means has main beam light receiving portions and sub-beam light receiving portions. The amount of light of the first or higher order diffracted beams when they are substantially focused on and reflected by a focus plane of the plurality of information recording planes is equal to or greater than the amount of light of the zero order diffracted beam when it is reflected without focusing by a non-focus plane other then the focus plane of the plurality of information recording planes. The invention provides an optical pickup head where offset is not generated in the TE signals even during tracking with the objective lens when a two-layered disk is used.

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 head device includes a diffraction grating for generating zero-order diffracted light and at least first-order diffracted light and provides a tracking error signal with a DPP method. The diffraction grating includes grating patterns with a nonuniform period or phase. The size of the first-order diffracted light converged on an optical recording medium is larger in the direction parallel to a tangent to the track than in the direction perpendicular to the tangent. P1/P0>PW2/PW1 is established, where PW1 represents the power that is required to record information on the optical recording medium, PW2 represents the maximum power that allows information recorded on the optical recording medium to be reproduced without being erased, P0 represents the light amount of the zero-order diffracted light converged on the optical recording medium, and P1 represents the light amount of the at least first-order diffracted light converged on the optical recording medium. This configuration makes it possible to detect a tracking error signal with reduced offset, even if a recordable optical recording medium having two information recording planes is used.

摘要： Tilt of an optical storage medium is stably detected even when then the guide groove pitch is reduced and recording capacity is increased. On a disk with continuous grooves of a pitch Gp, part of tracks Gn−1 and Gn+1 adjacent to opposite sides of an n-th track Gn is eliminated, forming an area where the groove pitch is equivalent to 2·Gp. A push-pull signal from the area of groove pitch Gp and a push-pull signal from the area of groove pitch 2·Gp are differentiated to obtain a tilt error signal. Tilt can therefore be detected even when groove pitch Gp is reduced and storage capacity is increased, and a highly reliable data recording and reproducing apparatus can be provided at low cost.

摘要： An online shopping system is provided for minimizing transportation costs by using a plurality of prestandardized delivery containers to eliminate waste in product delivery, and enhancing the convenience of users by automatically selecting a delivery container in accordance with the size of a selected product and clearly denoting information about an order closing time, a delivery source location, etc. When the user inputs the type and the quantity of a product, a delivery container which is optimal for storing the ordered product is automatically selected based on the volume of the product and an internal capacity of the delivery container, and a price of the selected delivery container is displayed. Thereafter, each time an additional product is ordered, a new delivery container which is optimal for storing all ordered products including the additional product is selected, and a price of the new delivery container is calculated. Information related to a price difference between a previously selected delivery container and the newly selected delivery container selected is obtained and presented to the user in accordance with prescribed display methods.
