Abstract

A servo writer of the invention writes a servo signal in a magnetic tape, reads and inspects the signal, and has a servo writer main body and a plurality of unit panels changeably loaded to a panel change unit provided at the main body according to a product class of the tape, wherein any of the unit panels has a servo write head for writing the signal in the tape and a write-sub-control mechanism for controlling a writing of the signal by the write head, wherein the write head and the sub-control mechanism write a predetermined signal in the tape, and wherein the main body has a signal main control mechanism for mainly controlling a writing of the signal in the tape by the write head, a servo read head for reading the signal written in the tape, and a signal inspection mechanism for processing and inspecting the signal.
