Abstract
A data recording and reproducing apparatus includes a rotary head for recording a signal on a tape-like recording medium while successively forming tracks thereon, and for reproducing a signal from the tape-like recording medium. Each of the tracks has a front margin area, an effective data area, and a rear margin area. A flag is generated which represents which of different speeds the rotary head rotates at. The generated flag is inserted into the signal before the signal is recorded on the tape-like recording medium by the rotary head. Thereby, the flag is recorded on the effective data area. A data rate of the signal recorded on the tape-like recording medium is maintained at a constant rate independent of which of the different speeds the rotary head rotates at. An amount of data recorded on the rear margin area is controlled in response to which of the different speeds the rotary head rotates at to cause the tracks to be equal in length independent of which of the different speeds the rotary head rotates at.
