Abstract: An optical disk apparatus for sequentially recording desired data per unit of a predetermined data quantity in response to an input command. The apparatus comprises an input means (3) for inputting the command and the data (51), a recording means for recording the data on an optical disk (2), and a control means (9) for controlling the operation of the input means (3) and the recording means (4) in response to the command, wherein the control means accepts the data quantity permissible for slipping correspondingly to a record command and then executes a slipping process within a range of such data quantity. In this apparatus, the control means (9) executes the slipping process on the basis of the result of monitoring a tracking error signal or a focus error signal. The apparatus is capable of exactly recording high transfer rate date, such as video data, in real time with certainty by a simplified structure.

Abstract: An optical disk apparatus for recording and/or reproducing user data on to and/or from an optical disk (12) includes an optical head (11) with a semiconductor laser (13) for irradiating a laser beam having a wavelength of approximately 680 nm or less to the optical disk (12) and having a lens (17) with a numerical aperture (NA) of approximately 0.7 or more and a working distance of approximately 560 µm or less. By utilizing such apparatus, a relatively large amount of data may be recorded onto the optical disk (12).

Abstract: The present invention is concerned with control and detection of a laser beam for an optical disc recording/reproducing apparatus in which the intensity of a return laser beam reflected by an optical recording medium of a recording laser beam used for forming pits (P) and recording data on the recording medium during the recording mode is detected and an error signal including focusing and tracking error signals of the recording laser beam is formed on the basis of a detection output of the intensity of the return laser beam within a predetermined time interval ( tau ) before the pit (P) starts to be formed by the recording laser beam on the recording medium to control the recording laser beam, and in which, when recording data on the optical recording medium having sub-data previously recorded thereon as pre-grooves with wobbling, these sub-data are detected on the basis of the detection output of the return laser beam within said predetermined time interval ( tau ) or within a predetermined time interval other than said predetermined time interval ( tau ).
