Abstract
Disclosed is a servo writer when, detecting an abnormality from servo signals written on a tape-shaped recording medium, such as a magnetic tape, corrects the abnormality through a simplified procedure, thereby allowing for an increase in the transport speed of media in the future. The servo writer includes a write head for writing servo signals, a verifying head positioned downstream of the write head in a transport direction of the tape, for reading the servo signals written by the write head in order to inspect the servo signal, an inspection section for checking whether or not the servo signals being read by the verifying head contain any abnormality, and an overwrite head positioned downstream of the verifying head in the transport direction, for overwriting a portion where the abnormality is detected by the inspection section.
