Abstract

PURPOSE:To improve the reliability of recording and reproducing data by running a magnetic tape until a terminal part of the magnetic tape is detected, when an unformat tape is detected, and executing its rewinding until an initial part of the magnetic tape is detected. CONSTITUTION:A magnetic tape is brought to quick traversing until a terminal part of a magnetic tape is detected, and while rewinding it at high speed, a format count value is read out intermittently, and when the format count values are coincident, an EOI sector is detected roughly by stopping the rewinding of a high speed, and also, by this operation, a magnetic tape is all wound up to one reel in order to read out a lead-in area, and thereafter, all wound up to the other reel by quick traversing, and furthermore, partially wound to one reel in order to detect the EOI sector. In such a state, by running of this magnetic tape, winding which conforms to a recording and reproducing device is executed. In such a way, winding disorder of the tape can be corrected.
