Abstract
A recording apparatus arranged to shift a recording head in a given direction relative to a record bearing medium and to perform recording in each shifted position. In positioning the recording head, the presence or absence of a record in each recording track on the medium is detected by checking them one after another in a direction reverse to the given direction from a given position. Then, the head is positioned at the first of consecutive blank recording tracks by positioning the head at a point determined by shifting the head to a given extent in the given direction from a position where the presence of a record is first detected among others by the checking operation.
