DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a recording and/or reproducing apparatus for a recording medium and a recording and/or reproducing method, which are adapted for allowing a recording and/or reproducing head and a recording medium to relatively undergo movement operations to thereby carry out recording of information signals with respect to the recording medium, or to carry out reproduction of information signals recorded on the recording medium. More particularly, this invention relates to a recording and/or reproducing apparatus for a recording medium and a recording/reproducing method therefor in which, at the time of recording of information signals with respect to the recording medium, reverse designation information for reversing relative movement direction of the recording and/or reproducing head and the recording medium at the time of reproduction of the recording medium is recorded to automatically reverse the movement direction of the recording medium on the basis of the reverse designation information, thus making it possible to reproduce information signals extending over the reciprocating directions.
BACKGROUND ART
Hitherto, tape recorders using a magnetic tape as a recording medium on which information signals such as music signals, etc. are recorded are known. In tape recorders of this kind, there are tape recorders having an automatic reverse function (hereinafter simply referred to as auto-reverse function depending upon circumstances) to automatically reverse the traveling direction of the magnetic tape from the forward (FWD) direction of the traveling state in the direction of the outgoing path to the reverse (REV) direction of the traveling state in the direction of the return (incoming) path, thereby making it possible to reproduce information signals recorded on the magnetic tape extending over the reciprocating directions in which the magnetic tape travels.
In such tape recorders having the auto-reverse function, as a system of reversing the traveling direction of the magnetic tape, there is known a system for detecting that a magnetic tape caused to undergo traveling operation is entirely wound onto one tape reel and rotation of a pair of tape reels is stopped to thereby reverse the traveling direction of the magnetic tape, and there is known a system for detecting a leader tape connected to the end portion of the magnetic tape to reverse the traveling direction of the magnetic tape.
Further, in the system of reversing traveling direction of the magnetic tape, there is also known a system of detecting that the magnetic tape has traveled to termination in the traveling state in the reverse (REV) direction to thereby reverse the traveling direction so that it is in correspondence with the forward (FWD) direction. In addition, there are also known tape recorders adapted for carrying out endless reproduction (playback) in which the operation for reversing the traveling direction of the magnetic tape from the forward (FWD) direction to the reverse (REV) direction and the operation for reversing it from the reverse (REV) direction to the forward (FWD) direction are combined so that a single magnetic tape can be repeatedly reproduced extending over reciprocating directions.
Meanwhile, in accordance with the conventional auto-reverse systems used in the conventional tape recorders, the operation for reversing the traveling direction in the vicinity of the tape end of the magnetic tape caused to undergo traveling operation is carried out in all systems. For this reason, in the case where the endless reproduction is carried out, the repetitive reproduction (playback) time of one endless reproduction operation in the reciprocating directions is determined by the length of the magnetic tape used. Further, in tape recorders of the auto-reverse system, in the case where a magnetic tape on which only music information having short time as compared to the recordable time is recorded is reproduced, portions where no music information is recorded would be unnecessarily reproduced.
