Problems solved by technology

In addition, when a retry due to an error is performed, the execution time of recording and reproduction becomes longer.
And, recording and reproducing carry out time lengthening like this, when the image of 1 frame can not be recorded or reproduced in the recording and reproducing time of 1 frame 33.34ms, the coma error (Japanese: コマラち) such a question

Embodiment Construction

[0021] Next, a preferred information recording and reproducing apparatus and information recording and reproducing method related to the present invention will be described in detail with reference to the drawings. In addition, the same reference numerals are assigned to the parts having the same functions in the drawings.

[0022] Embodiment 1

[0023] Fig. 1 is a block diagram of an information recording and reproducing apparatus according to Embodiment 1 of the present invention, and Fig. 2 is a diagram showing the structure of a frame memory of the information recording and reproducing apparatus according to Embodiment 1 of the present invention.

[0024]As shown in FIG. 1, this information recording and reproducing device has a 1394 interface 1 for receiving serial signals from a DV player 7, converting the serial signals into parallel signals and temporarily storing them in the frame memory 6, controlling the flow of the signals, and A disk controller 2 for recording or...

Abstract

When recording or reproducing a data, it is adapted such that first, from a position on a disc where a command has been issued thereby making it possible to record or reproduce the data, the data corresponding to each position is recorded or reproduced in the order and, thereafter as to a portion on the disc where the data has not been able to be recorded or reproduced, the data corresponding to its each position is recorded or reproduced. By this, it is possible to decrease a reduction in recording / reproducing implementation time owing to a rotation wait occurring by an overhead of the command or retry by an error, thereby shortening the recording / reproducing implementation time.

Description

technical field [0001] The present invention relates to an information recording and reproducing device and an information recording and reproducing method, in particular to the technology of recording or reproducing information on a disk information carrier. Background technique [0002] Currently, a disc device for recording or reproducing (regenerating) DV (Digital Video, digital television) format image signals on a disc is being discussed. In the above-mentioned disc device, when recording or reproducing continuous image data, the laser head and the disc are switched in the order of LBA (Logical Block Address, Logical Block Address) from the outer circumference of the disc to the inner circumference or from the inner circumference to the outer circumference. Data is recorded or reproduced simultaneously. [0003] At this time, it takes a lot of time for recording or reproduction because rotation wait due to overhead of commands and rotation wait due to retry due to err...
