Abstract
A method for performing a reproduction and search operation on a data recording and reproducing device of the helical scan type which includes a pair of recording and reproducing heads mounted on a rotary drum. The method includes the steps of: (a) during the reproduction operation, transporting the tape and rotating the rotary drum such that a relative speed between said tape and the heads is either a first relative speed or a second relative speed which is less than the first relative speed; and (b) during the search operation, transporting the tape at a speed substantially greater than a tape speed used during the reproduction operation and rotating the rotary drum at a speed such that a relative speed between the tape and the heads is equal to the second lower relative speed.
