Abstract

A recording method for recording an inputted digital signal on a recording medium in which track number data corresponding to the recorded digital signal is recorded by the steps of recording the inputted digital signal on the recording medium and updating the track number data corresponding to the digital signal recorded on the recording medium after an information changing point is detected by detecting at least one of a change of track number in the inputted digital signal, a change of index information, a continuity of reproduction time information, and an existence of audio data in the digital signal.

Claims

1. A recording method for recording an inputted digital signal on a recording medium in which management data corresponding to said recorded digital signal is recorded, comprising the steps of:

recording said inputted digital signal on said recording medium and detecting an information changing point in the inputted digital signal by detecting at least three of a change of track number in said inputted digital signal, a change of index information which is present a silence portion, a continuity of reproduction time information in the inputted digital signal, and an existence of silence data in said inputted digital signal; and

updating said management data corresponding to the digital signal recorded on said recording medium after said information changing point is detected.

2. A recording method according to claim 1, wherein:

said management data updating step is performed after setting a waiting state for a predetermined time from the point of a record starting time of said inputted digital signal.

3. A recording method according to claim 1, further comprising the step of:

detecting whether said inputted signal is a digital signal or not, before said recording operation to said recording medium starts.

4. A recording method for recording an inputted digital signal on a recording medium in which the inputted digital signal is outputted with sub-code data from a signal source in which the digital signal is recorded with the sub-code data, comprising the steps of:

(a) detecting whether the inputted signal is a digital signal or not;

(b) starting the recording of the digital signal on the recording medium if it is detected in step (a) that the inputted signal is a digital signal and setting an operation for changing a track number to a waiting state for a fixed time;

(c) if it is detected in step (a) that the inputted signal is not a digital signal, then detecting whether a mute section of the inputted signal continues for a predetermined period of time or not;

(d) determining a changing point of the track number as occurring if the mute section detected in step (c) continues for the predetermined period of time and then updating the track number of data to be recorded on the recording medium;

(e) detecting, after step (b), a track number changing point;

(f) detecting, after a track number changing point is detected in step (e), whether or not an index information of the sub-code data arrives in a head position of an inputted next digital signal; and

(g) if it is detected in step (f) that the index information arrives at the head position, updating the track number of data to be recorded in the recording medium.

5. A recording method for recording a digital signal, which is reproduced with sub-code information from a first recording medium in which the digital signal is recorded with the sub-code data, to a second recording medium, comprising the steps of:

(a) beginning recording of the digital signal read from the first recording medium to the second recording medium and pausing changing of a track number to be recorded in the second recording medium for a fixed waiting time;

(b) determining whether the signal which is reproduced from the first recording medium is a digital signal or not;

(c) if the signal is detected in step (b) as not being a digital signal, detecting a mute section of the digital signal and determining whether the detected mute section continues for a predetermined period of time or not;

(d) if the mute section detected in step (c) continues for the predetermined period of time, determining that a changing point of the track number of sub-code outputted with the digital signal from the first recording medium has occurred;

(e) if it is detected in step (b) that the signal is a digital signal, detecting a track number changing point and then detecting whether an index information of sub-code outputted with the digital signal from the first recording medium arrives at a head position of the next reproduced digital signal from the first recording medium or not; and

(f) after detecting the arrival of the index information in step (e), detecting if the signal is audio data and, if the signal is audio data, updating the track number of data to be recorded to the second recording medium.

6. A recording method for recording an inputted signal on a recording medium in which the inputted signal, if it is a digital signal, is outputted with sub-code data from a signal source in which the signal is recorded with the sub-code data, comprising the steps of:

(a) detecting whether the inputted signal is a digital signal or not;

(b) if it is detected in step (a) that the inputted signal is not a digital signal, starting recording of the inputted signal on the recording medium while simultaneously detecting whether a mute section of the inputted signal continues for a predetermined period of time or not;

(c) determining that a changing point of the track number has occurred if the mute section detected in step (b) continues for the predetermined period of time and then updating the track number of data to be recorded on the recording medium;

(d) if it is detected in step (a) that the inputted signal is a digital signal, starting the recording of the inputted signal on the recording medium and setting an operation for changing a track number to a waiting state for a fixed time;

(e) detecting, after step (d), a track number changing point;

(f) detecting, after a track number changing point is detected in step (e), whether or not an index information of the sub-code data currently equals the predetermined beginning of an index string; and

(g) if it is detected in step (f) that the index information equals the predetermined beginning of an index string, updating the track number of data to be recorded in the recording medium.

7. A recording method for recording a digital signal, which is reproduced with subcode information from a first type of recording medium in which the digital signal is recorded with the sub-code data, to a second recording medium, comprising the steps of:

(a) determining the type of the first recording medium and setting a corresponding type flag;

(b) beginning recording of the digital signal read from the first recording medium to the second recording medium and pausing changing of a track number to be recorded in the second recording medium for a fixed waiting time;

(c) detecting the type flag and if the type flag is set for other than a compact disc (CD) or a magneto-optical disc (MD), then determining if a muted section occurs in the inputted signal for a predetermined of time;

(d) if it is detected in step (c) that the muted section occurs for the predetermined of time, updating the track number of the data being recorded on the second recording medium;

(e) if at step (c) the type flag of a CD or an MD is detected, then detecting a track number changing point;

(f) after a track number changing point is detected at step (e), then detecting whether an index information of sub-code outputted with the digital signal from the first recording medium arrives at the leading position of the next reproduced digital signal from the first recording medium or not; and

8. A recording method for recording a digital signal according to claim 7 further comprising the step of detecting if the type flag is set to MD after detecting the track number changing point in step (f) and then if it is detected that the type flag is not set to MD, it is then detected whether or not a minute information (MIN) is equal to "00" and, if so, whether or not a frame information of the inputted signal continues successively for three times before proceeding to step (g).
