Abstract: An objective lens causes birefringence, which causes wave aberration in outgoing light from the objective lens. A coated objective lens has a dielectric multilayer film that can reduce astigmatism component of the wave aberration to 5 m? rms or smaller when 10 m? rms or larger astigmatism component of wave aberration is generated.

Abstract: The invention relates to recording methods for recording information on a dual layer recordable disk, and to corresponding recording devices. In one such method and recording device the OPC-area is variably located on a layer of the disk. In a preferred embodiment the OPC-area is located relative close to the radius where the data stream switches from the first layer to the second layer. This reduced additional time required for jumping to a fixed OPC-area. Furthermore, in another such method and device the information to be recorded is equally divided over both layers of the dual layer disc. This avoids additional time required for finalization.

Abstract: A reproducing device includes a detection circuit and an integration circuit. The detection circuit detects a push-pull signal PP. The integration circuit carries out integration processing with respect to one or greater frames of the push-pull signal, and carries out binarization processing with respect to integration results thus obtained, thereby detecting sub data. In the integration circuit, the more the frames to be used for detecting sub data is, the higher the accuracy of the detected sub data is. The reproducing device further includes a control circuit for controlling the total number of the frames to be used for generating valid sub data in the integration circuit. The control circuit controls the total number of the frames in accordance with a result of an error correction made by an error correction circuit.

Abstract: The present invention is a dubbing device for dubbing data from a portable first recording medium such as a CD-DA (compact disc digital audio) to a second recording medium such as a hard disk drive (HDD), in which dubbing to the second recording medium with a large capacity is automatically carried out when reproducing data from the first recording medium. When data is reproduced from the first recording medium, database means is searched on the basis of identification information for the first recording medium and execution control of dubbing is performed in accordance with the result of search for recording history information. For example, whether or not data to be reproduced from the first recording medium has been already recorded on the second recording medium is discriminated, and dubbing is carried out if the data to be reproduced data has not been recorded on the second recording medium.

Abstract: According to one embodiment, a disk drive configured to write data to a disk being rotated by a spindle motor has a synchronous clock generator that generates a synchronous clock to use during the write operation. The synchronous clock generator inputs the rotational acceleration of the spindle motor, as feed-forward control value, to the feedback control system provided in the drive disk, thereby generating a clock that is synchronous with the rotational speed of the disk.

Abstract: A recording method, particularly suitable for use in a digital video-camera, is described according to which a digital signal (10), deriving from the encoding of an audio-video signal is temporarily stored in a buffer (11) and from there recorded in a dual layer DVD (12) in successive recording intervals (22) or packets. The start/stop of a recording interval is normally controlled according to the level (15) of filling of the buffer. The digital signal is partitioned in portions that need to be entirely recorded on one single layer, and this triggers the need for a layer jump independently from the level of filling of the buffer. In order to avoid starting a layer jump with the buffer already partly filled, and therefore having a short non-recording interval (23) when time is mostly needed for calibrations, it is proposed to adjust the resolution in the encoding of the audio-video signal so as to have the buffer close to empty when the layer jump occurs.

The recording medium according to an embodiment includes a data area storing at least multiple audio streams in at least one portion thereof, the multiple audio streams being multiplexed, each audio stream being a transport stream and stored as one or more packets, each packet having a packet identifier, and the packets of a same audio stream having a same packet identifier, and a management area including management information for managing reproduction of the multiple audio streams.

Abstract: An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.

Abstract: It is possible to manage an empty region in a disc partition while satisfying an inhibit matter of the ROM standard not recording a space bit map describer (SBD). The SBD is recorded upon disc initialization and additional recording into the partition is performed by using the SBD regardless of the access type in the device. When ejecting the disc, pointer information to the SBD recorded in the partition describer (PD) is hacked up in the SBD pointer information save file or save data and then the pointer information is erased. Upon disc recognition, the existence of the save file/data is confirmed and the SBD is restored.

Abstract: An information recording system, where new data recording is started from LRA (old) and a record error is detected, at position P0, an extent is closed and the record position is made to jump from the position P0 to position P1. Further, a new extent is set, at the position P1 so that the data recording is continued. Further, a range from the position P0 where the record error was detected to the position P1 where the new data recording was started is registered, as a defect sector.

In an optical recording method for recording information on a multilayer optical recording medium having a plurality of recording layers by irradiating the recording layer with a beam spot, when a defect area is detected while the information is recorded on a specific recording layer selected from the plurality of recording layers, an escape recording layer which is selected from among the other recording layers except for the specific recording layer is irradiated with the beam spot to continue recording the information.

Abstract: When recording recording information by forming on a recording medium a recording mark whose mark length is an integral multiple of the reference mark length according to a recording signal generated from a recording information signal, this method performs a process of: generating, after recording compensation recording information on the recording medium, a reproduction signal by reading out the compensation recording information; generating from the reproduction signal a reproduction clock whose cycle corresponds to the reference mark length; setting a signal level suitable for binarization determination of the reproduction signal as a distribution reference level, according to the difference in variation between white and black levels of the reproduction signal; and calculating the recording correction value for correcting the compensation recording signal, so that the reproduction signal becomes closer to the distribution reference level around a target cross timing determined based on the reproduction c
