ABSTRACT:
An analog/digital compatible reproducing system is disclosed, particularly a stationary head system using a digital recorded magnetic tape having a plurality of n, digital data recorded tracks. An analog recorded magnetic tape has a first analog recorded track and a second analog recorded track between which a guardband of a certain width is provided. Signals are reproduced from the digital recorded magnetic tape by driving n reproducing magnetic head elements respectively corresponding to the n digital data recorded tracks. The analog recorded magnetic tape is reproduced by driving a plurality of m reproducing magnetic head elements of said n reproducing, magnetic head elements, corresponding to the first and second recorded tracks so that common outputs can be produced from the m reproducing magnetic head elements. There is also disclosed a tape cassette used in such system.
