ABSTRACT:
A method of, and a system for, writing start marks in selected positions between tunes or like segments of information that have been recorded on digital audio tape, preparatory to the writing of serial program numbers in such selected positions. A position select switch is to be actuated for selecting a position on the tape between any two information segments when a transducer comes to such a position on the tape in the course of tape playback. The time code data that is read on the tape when the position select switch and which, therefore, represents the selected tape position is written on a random access memory built into a system controller of the apparatus and is further visibly displayed in hours, minutes, seconds and frames on display windows. Playback is continued for a preassigned brief time after the actuation of the position select switch. Then, with the transducer relatively returned to the selected tape position, a start mark is written in that position. The display windows continue the display of the selected tape position until the start mark is written. The system controller is additionally programmed to permit the amendment of the selected tape position and the confirmation of whether the selected, or amended, tape position is appropriate for writing a start mark and, later, a program number.
