AI Technical Summary

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

[0044] 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.

[0045] 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 etc. The memory 10...

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. Thereby the bit rate of transmitting is assured.

Description

technical field [0001] 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. [0002] In addition, the present invention relates to a data editing method and device for disc recording media, and particularly to a data editing method and device capable of ensuring bit rate and real-time performance during AV data editing. Background technique [0003] In recent years, due to the appearance of large-capacity storage media such as magnetic disk, optical disk, magneto-optical disk and DVD (digital video disk), a large amount of data can be recorded and stored on a storage medium. Copying operations to move all or part of the data recorded on such a large-capa...
