SERVO WRITER AND SERVO WRITING PROCESS |
摘要 |
A servo writer according to the present invention is a servo writer which writes a servo signal on a servo band of a magnetic tape. It comprises a magnetic tape driving system in which a magnetic tape supplied from a supply reel is taken up by a take-up reel to drive the magnetic tape; a DC erasing head which is slidably in contact with said driving tape and which DC-magnetizes said servo band with imparting an azimuth relative to said servo band; and a servo signal writing head provided on a downstream of said DC erasing head in the driving direction of the magnetic tape, which is slidably in contact with said driving tape and which magnetizes the servo band by a magnetizing force having a component with a reverse magnetizing force relative to the magnetizing force of the DC erasing head in the lengthwise direction of the magnetic tape.
