ABSTRACT:
A recording and reproducing apparatus according to the invention has: at least a pair of rotary heads having different azimuth angles; a run controller for controlling the run of the magnetic tape; and a recording timing controller for controlling so that the recording by the rotary heads is performed at the first period when digital data having a first data rate is inputted, wherein the digital data is recorded on the magnetic tape at a recording timing. The recording and reproducing apparatus also has a memory for storing the digital data which is supplied from the outside, a reader for reading the digital data stored in the memory, and a signal processor for executing a predetermined process to the digital data read from the memory. When digital data having a second data rate which is different from the first data rate is inputted, the recording timing controller and the reader execute respective processes at an operating speed based on the ratio of those rates and the run controller controls the speed of the magnetic tape based on the data rate ratio.
