Abstract
Open spool reels (18) of magnetic tape (7) are recorded with a plurality of different programmes interspersed with recordings in a different form (typically as interruptions to the sync track), representing data information concerning the programme material and production history of the recording. The data (6) recorded on the tape (7) is read by a transducer (39) on a cassette loading machine (30) and used to control the operation of the loading machine, identifying the length of tape and the position on the tape where splices between the magnetic tape (7) and leader tape in cassette shells is to be made. The data (6) also controls a label printer (46) to produce a printed label, typically in bar code form, carrying information representing the programme material on the tape loaded into the cassette. This label is automatically applied to the cassette shell as part of the cassette loading operation so that each cassette is securely provided with external easily read information identifying the programme content thereby avoiding the necessity for individual playback of a tape to identify its programme content.
