Abstract
PURPOSE:To record a large quantity of highly reliable data within a short time by using a reproduction head and a verifying head in common. CONSTITUTION:A second rotary head H2 reproduces data from a track which it pursues and traces during a data recording by a first rotary head H1, and corresponding to the error-occurrence condition of thus reproduced data, the same data as that recorded on the track is recorded in another track by the first rotary head H1. With such a constitution, in the event of an error occurring in recording data, the data can be re-recorded without stopping the running of a tape-shaped recording medium. As a result, in addition to the use of the rotary heads, it is made possible that a large quantity of highly reliable data can be recorded within a short time.
