S01430 METHOD AND APPARATUS FOR RECORDING DIGITIZED INFORMATION ON A RECORD MEDIUM ABSTRACT OF THE DISCLOSURE At least one channel of digitized information is recorded in a selected number of data tracks by a record medium. The digitized information is encoded, modulated and then recorded in a predetermined number of tracks. For example, if n channels of digitized information are to be recorded in m data tracks, then each channel is recorded in ? data tracks (m?n). A control signal is generated to include control data representing at least one of the following: (a) the number of data tracks in which each channel of digitized information is recorded, (b) the encod- ing scheme used to encode the information, (c) the type of modulation used to modulate the encoded information and (d) the relative speed of movement of the record medium. The control signal is recorded in a separate control track. Thus, the control signal represents the particular format in which the digitized information is recorded. -i-
