装置。[Claims for Utility Model Registration] A rotary drum having a recording/reproducing head and a plurality of erasing heads, and when the range erased by one erasing head is one track, the erasing frequency is different for each adjacent track. In a magnetic recording/reproducing device, a beat frequency detection means detects the beat frequency of two erasing frequencies generated between adjacent tracks due to track deviation, and a beat frequency detected by the beat frequency detection means is used to detect the beat frequency of a magnetic tape. A tracking device comprising: a running speed control means for controlling the running speed; and a rotational speed control means for controlling the rotational speed of a recording/reproducing head and an erasing head based on a beat frequency.
