ABSTRACT:
An apparatus and method for magnetically transducing information with respect to select portions of selected of a multitude of parallel record tracks on an elongated magnetic record member such as a flexible magnetic belt which is supplied from a coiled formation thereof stored in an elongated magazine or cartridge. The magazine is removably secured in or against a housing containing transducing means and means for automatically engaging a free end of the magnetic belt and driving same from its housing along a select path to position a select portion of the length of the belt at a transducing location. A magnetic transducer is automatically aligned with a select track of the belt and is driven along such select track while it is energized to either record information along or reproduce previously recorded information from the select portion of the select track of the belt. If the select portion of the belt is located a distance from the free end thereof, the free end of the belt and a select portion thereof is allowed to roll or fold into a container for temporary storage until transducing operations are finished and the belt is automatically returned to its container. The invention also resides in improvements in the construction of the magazine storing the belt and the method employed to position the magazine, remove and drive its belt and locate same with respect to the transducing means.
