Abstract:
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.
Abstract:
To measure a lateral shift of running magnetic tape caused by a lateral movement of the magnetic tape which occurs while the magnetic tape is running, a fixed write head H1 of a measurement apparatus 10 magnetizes part of the running magnetic tape MT in a section of the apparatus 10 where the magnetic tape MT is free from restriction on lateral movement; a pair of guides 14, 14 in a tape guide unit of the apparatus 10 is located downstream of the fixed write head H1 to restrict the lateral movement of the magnetic tape MT; and a fixed read head H2 reads information recorded on the magnetic tape MT in the tape guide unit.
