| Summary: | The servo signal recording device records a servo signal onto a magnetic tape. The device includes a transporting unit for transporting the magnetic tape along its lengthwise direction, a recording unit for recording the servo signal onto the transported magnetic tape, a detecting unit for detecting an edge of the magnetic tape at a time when the servo signal is recorded and an adjusting unit for adjusting a recording position of the servo signal along a crosswise direction of the magnetic tape in accordance with a detection result of the edge of the magnetic tape by the detecting unit. The servo signal verifying device verifies a servo signal recorded onto a magnetic tape. The device includes a reproducing unit for reproducing the servo signal, a detecting unit for detecting an edge of the magnetic tape at a time when the reproducing unit reproduces the servo signal and a calculating unit for calculating a verification result of the servo signal recorded onto the magnetic tape using a reproduction result of the servo signal and a detection result of the edge. |
