ABSTRACT:
An apparatus and method for reproducing digital information recorded in tracks of a recording medium, such as a magnetic tape. A track number and a synchronization block number may be utilized to detect a trace phase. Such trace phase and a reference trace phase may be used to produce a phase error which is used to control the tape speed. As a result, the tape traveling speed may be controlled with a relatively high accuracy.
