Recording and reproducing apparatus and method
View Patent ↗A signal is recorded on and reproduced from a first tape-like storage medium. At least one indexing signal is recorded on the first storage medium. Or, at least one indexing signal already recorded on the first storage medium is detected. The location of the indexing signal is determined as an indexing position. The signal that has been recorded on the first storage medium is recorded on a randomly accessible second storage medium from the indexing position for a specific period.
1. A recording and reproducing apparatus comprising:
a first recorder and reproducer to drive tape-like first storage medium for recording a signal on and reproducing the signal from the first storage medium, record at least one first indexing signal on the first storage medium or detect at least one second indexing signal already recorded on the first storage medium, and determine the location of the recorded first or second indexing signal as an indexing position;
a second recorder and reproducer to record a signal on and reproduce the signal from a randomly accessible second storage medium; and
a controller to control the second recorder and reproducer to record the signal that has been recorded on the first storage medium on the second storage medium from the indexing position for a specific period P, period P equaling (|L−2C|+L)/2V in which L is a length of the first storage medium, V is a fast forward/backward feeding speed for the first storage medium and C is the current location of the first storage medium from the head or the end of the tape-like first storage medium.
2. The recording and reproducing apparatus according to claim 1 , wherein the controller controls the second recorder and reproducer to reproduce the signal from the second storage medium from the indexing position until the first storage medium driven by the first recorder and reproducer reaches at least the indexing position by fast forward/backward feeding for reproduction of the signal from the indexing position on the first storage medium.
3. A recording and reproducing method comprising the steps of:
recording a signal and at least one indexing signal on a tape-like first storage medium;
determining the location of the indexing signal as an indexing position; and
recording the signal that has been recorded on the first storage medium on a randomly accessible second storage medium from the indexing position for a specific period P, period P equaling (|L−2C|+L)/2V in which L is a length of the first storage medium, V is a fast forward/backward feeding speed for the first storage medium and C is the current location of the first storaae medium from the head or the end of the tape-like first storage medium.
4. The recording and reproducing method according to claim 3 further comprising the step of reproducing the signal from the indexing position on the second storage medium until the first storage medium reaches at least the indexing position by fast forward/backward feeding for reproduction of the signal from the indexing position on the first storage medium.
5. A recording and reproducing method comprising the steps of:
detecting at least one indexing signal already recorded on a tape-like first storage medium;
determining the location of the indexing signal as an indexing position; and
recording a signal that has been recorded on the first storage medium on a randomly accessible second storage medium from the indexing position for a specific period P, period P equaling (|L−2C|+L)/2V in which L is a length of the first storage medium, V is a fast forward/backward feeding speed for the first storage medium and C is the current location of the first storage medium from the head or the end of the tape-like first storage medium.
6. The recording and reproducing method according to claim 5 further comprising the step of reproducing the signal from the indexing position on the second storage medium until the first storage medium reaches at least the indexing position by fast forward/backward feeding for reproduction of the signal from the indexing position on the first storage medium.
