摘要：
A data stream is recorded and reproduced and a recording medium for the same are adapted to record in a control track an identification mark for identifying a specific track within a unit of plural tracks by superposing the identification mark upon a control pulse. A magnetic head travels along a predetermined path in the unit of plural tracks during a high-speed playback operation by phase-locking a rotational phase signal of a cylinder with a divided signal of the control pulse having a specific phase according to the reproduced identification mark.
