ABSTRACT:
An input digital signal is recorded on inclined tracks on a magnetic tape. The tape has a length L divided quarterly. A leading portion L/4 is reserved for general data, while the remaining portions are reserved for continuous data. The general and continuous data are recorded as SYNC blocks on different tracks. A number of general data SYNC blocks of one track from a basic unit which is divided into sub-units. The general data sub-units are arranged in the same format as the continuous audio data such that the general data is recorded in the same format as the continuous data. The data rates of the input digital signal which includes the general and continuous data are supplied to a mechanism controller which controls a buffer, a frame segmenting circuit and a tape head mechanism according to the data rates of the general and continuous data such that the data is recorded at a standard rate. In the alternative, the data may be recorded at the standard rate by forming the data into packets to be recorded and controlling the number of bytes in the packets.
