Information processing device, and information processing system

Disclosed are an optical disk recording and reproducing apparatus, a remote controller, and a content management method capable of allowing a user to easily confirm contents recorded on an optical disk, wherein an optical disk is integrally provided with a read-only RFID tag that records only a disk ID to identify the optical disk as an individual. When a content is recorded on the optical disk, a video recorder records disk management information including the disk ID of the optical disk and index information about the content. After the content is recorded, a remote controller noncontactly reads the disk ID from the RFID tag of the optical disk and transmits the disk ID to the video recorder. The video recorder extracts index information corresponding to the received disk ID from the disk management information and displays the index information in a list.

Optical disk recording and reproducing apparatus, remote controller, and content management method

In a recording medium, the physical characteristic information of the recording medium, and more specifically, the configuration (shape and size) and the moment of inertia of the disc, is recorded. This enables a recording apparatus or a reading apparatus to easily and correctly determine the physical characteristics of the disc, and thus to perform suitable settings for the recording or reading operation.

Recording medium, recording apparatus, and reading apparatus

An optical disk driving apparatus includes a control computer, and the optical disk driving apparatus acquires a wobble signal. The control computer calculates an average period of a binarized wobble signal and a variance of the period of the binarized wobble signal. The control computer determines whether the calculated average period satisfies the specifications of DVD-R or DVD-RW and determines whether the calculated variance is below a predetermined level.

Optical disk driving apparatus and method, and recording medium and program used therewith

An optical disc having a power calibration area for calibrating the power of a data recording laser beam. The power calibration area is provided at an inner peripheral part of the disc and has test areas and count areas. The test areas are provided to accomplish trial writing of data, and the count areas are provided to record data representing the use condition of the test areas. Data is recorded on the optical disc, while calibrating the data recording laser beam. The number of the test areas is increased in accordance with an increase in the recording density of the optical disc. The optical disc may be a double-density CD. In this case, the disc has 800 to 1200 test areas. The test areas have the smallest possible size, and the count areas are provided in the smallest possible number. Therefore, the disc can have sufficiently large data regions. Thus, the power of the data recording laser beam can be therefore adjusted many times. The amount of data that can be recorded on the optical disc therefore increase.

Optical disc, data-recording apparatus and data-recording method

Physical addresses of the recording areas provided on an optical disc are represented in a time-axis data format and in a binary data format. The physical address value gradually increases from the inner part of the disc to the outer part of the disc, while the formats remain in one-to-one correspondence over the recording areas. The distance the optical head must move to reach a target recording area can therefore be calculated easily independently of where on the disc the optical head is located, enabling the optical head to quickly access the target recording area.

Optical disc and optical disc apparatus

To enable a plurality of types of optical discs different in recording density from each other and quickly getting &ldquo;ready&rdquo; for writing and/or reading data to and/or from each of such optical discs, various controlling conditions requisite for the data writing and reading operations are stored in a memory for both optical discs having first and second recording densities, respectively. For a shorter time up to a &ldquo;ready&rdquo; state for data write or read, a controller makes an instant discrimination, based on the pattern of a sync signal &ldquo;SYNC&rdquo; included in an ATIP wobble signal supplied from an ATIP decoder, between the optical disc having the first recording density and that having the second recording density, reads, from the memory, controlling conditions corresponding to the result of the disc type discrimination, and sets operating parameters for each component of the optical disc drive.

Optical disc drive, and recording/reproducing method

Within a sub-code to be recorded in a recording medium, the physical characteristics of the recording medium are recorded. This enables a recording apparatus or a reading apparatus to easily and correctly determine the physical characteristics of the recording medium by reading the sub-code. The physical characteristic information includes information concerning the material, the disc type, the linear velocity, the track pitch, the moment of inertia, and the size/configuration of the recording medium. It is thus possible to easily and correctly determine the physical characteristics of the disc (or unit area) while maintaining the compatibility with known recording media.

A low-speed focus servo operation in which an objective lens is moved slowly is performed in a start process that is executed after mounting of an optical recording medium. On the other hand, a high-speed focus search operation in which the objective lens is moved fast is started when focusing is lost in a state that a focus servo operation is being performed. In the high-speed focus search operation, the focus servo characteristic is set to a modified version of a characteristic that is determined by a calibration operation that is performed in the start process.
