Abstract:
A recording and reproducing apparatus for recording a video signal and an indexing signal to separate video signal areas and subcode areas, respectively, of diagonal tracks formed on a tape by a rotating head, said apparatus comprising:tape drive means for driving the tape;an add command generator for generating an add command to add said indexing signal at a requested position;an indexing signal control for setting and resetting said indexing signal;recording means for recording the video signal to the video signal area and the indexing signal, if any, to a subcode area of each track of the tracks; andediting control means for controlling said indexing signal control in response to said add command, such that the tape is rewound past said requested position for a first predetermined length, after which the tape is driven in a forward direction for a second predetermined length shorter than said first predetermined length, the tape then being further driven in the forward direction for a third predetermined length equal to a difference between said first predetermined length and said second predetermined length for recording the tape with the indexing signal, corresponding to a reset state, until the tape reaches said requested position, the tape being further driven in the forward direction for recording the tape with the indexing signal, corresponding to a set state, for a fourth predetermined length, the indexing signal being preserved as long as a leading edge of the indexing signal does not appear within a predetermined distance.
