Abstract

An information recording and reproducing apparatus (S) is provided with: a reproducing device (8) for reproducing information, which is recorded on a record medium (9) in advance; a compressing device (5, 6) for compressing the reproduced information to reduce an information amount of the reproduced information and generating a compression information; and a recording device (8) for re-recording the generated compression information onto the record medium.

Claims

1. An information recording and reproducing apparatus comprising:

a reproducing device for reproducing information, which is recorded on a record medium in advance;

a compressing device for compressing the reproduced information to reduce an information amount of the reproduced information and generating a compression information;

a recording device for re-recording the generated compression information onto the record medium; and

a controlling device for controlling said recording device to

(i) temporarily record the generated compression information onto a second record position, which is within an area where the reproduced information has never been recorded,

(ii) re-record the temporarily recorded compression information onto a first record position, which is within an already-recorded area on the record medium where the reproduced information has been recorded when said reproducing device finishes reproducing the information larger by a predetermined amount than the temporarily recorded compression information, and

(iii) then record the compression information, which is newly generated by said compressing device, onto the second record position, which is within the area where the temporarily recorded compression information has been temporarily recorded.

2. The information recording and reproducing apparatus according to claim 1, further comprising a temporarily recording device for temporarily recording the generated compression information onto a second record position, which is within a area where the reproduced information has never been recorded, wherein

the controlling device controls said temporarily recording device to record the compression information, which is newly generated by said compressing device, onto the second record position, which is within the area where the temporarily recorded compression information has been temporarily recorded.

3. The information recording and reproducing apparatus according to claim 1, wherein

reproducing operation by the reproducing device and recording operation by the recording device are executed simultaneously and parallel to each other.

4. The information recording and reproducing apparatus according to claim 1, wherein

the controlling device controls recording the temporarily recorded compression information onto the first record position such that the temporarily recorded compression information is recorded sequentially from a lead position of the already-recorded area on the record medium in which the reproduced information has been recorded.

5. An information recording and reproducing apparatus comprising:

a reproducing device for reproducing information, which is recorded on a record medium in advance;

a compressing device for compressing the reproduced information to reduce an information amount of the reproduced information and generating a compression information;

a recording device for re-recording the generated compression information onto the record medium; and

a controlling device for controlling said recording device to

(i) temporarily record the generated compression information onto a second record position, which is within a area where the reproduced information has never been recorded,

(ii) re-record the temporarily recorded compression information onto a third record position, which is within a non-recorded area on the record medium where the reproduced information has been not recorded when said reproducing device finishes reproducing the information larger by a predetermined amount than the temporarily recorded compression information, and

(iii) then record the compression information, which is newly generated by said compressing device, onto the second record position, which is within the area where the temporarily recorded compression information has been temporarily recorded, wherein

the controlling device controls recording the temporarily recorded compression information onto the third record position such that the temporarily recorded compression information is recorded sequentially from a lead position of the non-recorded area on the record medium in which the reproduced information has not been recorded, in the condition that the information is originally recorded on the record medium.
