ABSTRACT:
A method for detecting the leading and trailing ends of a video tape, which is capable of achieving an accurate detection without using any separate detecting means. The method includes the steps of determining whether or not the video tape runs at a high speed, counting the number of CFG signals for a current revolution of a reel adapted to run the video tape, when it is determined that the video tape runs at a high speed, inputting the counted number of CFG signals to a neural fuzzy function previously extracted in accordance with a learning procedure, thereby determining whether or not the video tape has run to the leading or trailing end thereof, executing a reproduction operation for the video tape when it is determined that the video tape has run to the leading or trailing end thereof, and determining whether or not any signal is reproduced from the video tape during the reproduction operation, and stopping the running of the video tape when it is determined that there is no signal reproduced from the video tape during the reproduction operation.
