Problems solved by technology

Therefore, there are the following problems: the management between the data track and the replacement track becomes complicated, a large number of track seeks are generated when the data is recorded and played back, and the desired bit rate cannot be obtained.
As a result, the number of seeks increases and the bit rate decreases because continuous playback is not possible
In addition, when processing AV data, there is still the problem of interruption of motion and destruction of real-time performance.

Embodiment Construction

[0045] A method of reproducing data on a disk recording medium and a disk recording apparatus according to a first embodiment of the present invention will be described below with reference to the drawings.

[0046] Figure 5 The configuration of the disc recording and reproducing apparatus in this embodiment is shown. exist Figure 5 Among them, the first disk drive A101 and the second disk drive B102 respectively read and write to the disk recording medium, and are connected to the control unit 104 . The operation unit 103 accepts an instruction such as copy input by the user, and outputs it to the control unit 104 . The control unit 104 is composed of a CPU, etc., and has a system control unit 105 that controls the entire device, a drive control unit 106 that controls the disk drives 101 and 102, a memory control unit 107 that controls the memory, and manages the image screen or file content recorded on the disk. The document management department 108 and so on. The mem...

Abstract

A method for copying data in disk recording media, and disk recording apparatus. At copying data recorded in a disk to another disk, occurrence of seek at the copy source is eliminated or suppressed below a specified value during reading data to reduce read time. At the target disk, data is rearranged according to video scenes or files, or file control information is rewritten to maintain the data structure of the copy source, thus the bit rate of transmission is ensured.

Description

[0001] This application is a branch of a patent application with an application date of May 14, 1999, an application number of 99106715.0, and an invention titled "Data duplication method, data recording method, data editing method, and disk recording device for disk recording media". case application. technical field [0002] The present invention relates to a data duplication method of a disc recording medium and a disc recording device, and more particularly to a data recording and reproducing device for a disc recording medium using a disc recording medium in which a track of recording data is divided into blocks (sectors) of a predetermined length. Replication method and disc recording device. [0003] Furthermore, the present invention relates to a data recording method on a disk recording medium, and more particularly, to a data recording method on a disk recording medium capable of ensuring a bit rate of input and output during data recording and reproduction. [0004...
