摘要： A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.

摘要： A recording apparatus for recording compressed video data has compressed video data generator for generating a compressed video data having a plurality of intra frames each of which has no cross-reference to any other frames, and bidirectional interpolated frames and predictive frames each of which has cross-reference to other frame. In the first cycle operation, address detector detects addresses of the intra frames and stores the detected addresses in a memory. A scan information generator generates, with reference to the stored addresses in the memory, scan information for an independent frame including one or two addresses of advanced intra frames and one or two addresses of previous intra frames. The scan information is inserted to each frame and then recorded on a disk. During the reproduce of the disk, the scan information is detected to have a quick access to the intra frame located near by.

摘要： An optical disk device which highly precisely positions a disk tray in an ejection position is provided. A controller of an optical disk device drives the disk tray from a storage position toward an exposed position. When a position immediately before the ejection position is detected by a detecting switch, the velocity is reduced, to allow the disk tray to contact a mechanical stopper, for positioning. The controller measures a movement time to the position immediately before the ejection position, and adjusts the drive voltage to increase or decrease the drive voltage for contact with the mechanical stopper according to the measured time.

摘要： An optical disk drive capable of reproducing data even when defects, such as flaws or stains, are present in the disk. A system controller of an optical disk drive reproduces data by setting the maximum speed in accordance with the type of an optical disk, an amount of side-to-side runout, and the like. When reproduction of data becomes impracticable for reasons of meandering of a track, or the like, in the middle of reproduction of data, the rotational speed is decreased, and a retry is performed. However, when reproduction of data becomes impracticable for reasons of flaws or stains, the rotational speed is reversely increased, and a retry is performed.

摘要： An optical disk device which quickly detects that a transparent disk is loaded is provided. When an optical disk is loaded, a drive controller of an optical disk device drives a spindle motor and checks existence of an optical disk based on a driving result. In addition, the drive controller drives an optical pickup to apply a focus control, to detect whether or not focusing is possible. When it is determined from the driving result that there is an optical disk and that focus is not possible, the drive controller judges that the optical disk (D) is a transparent disk.

摘要： An optical disk drive capable of reproducing data even when warpage is present in an optical disk. A system controller of the optical disk drive reproduces data by setting a maximum speed in accordance with the type of an optical disk, an amount of side-to-side runout, or the like. In the meantime, when a read error arises as a result of trial reproduction being performed at an outer radius of the disk at startup, warpage is determined to be present in the optical disk, and a limitation on the maximum speed is raised. The rotational speed is set to allowable maximum speed of the optical disk drive, and warpage is corrected by means of centrifugal force. When reproduction becomes impracticable for reasons of meandering of a tack, or the like, during the course of reproduction of data, the rotational speed is decreased, to thus perform a retry.

A time interval ti at which the buffer memory becomes full is measured, and the time interval ti is compared with a predetermined lower limit value t1 and a predetermined upper limit value t2. When a relationship of ti>t2 stands, rotational speed is increased. When a relationship of ti
