1. A method of writing servo tracks on tape which comprises irradiating a first end of an optical fiber bundle comprising a plurality of optical fibers arrayed in parallel with each other with laser light, transmitting the laser light emitted from a second end of the fiber bundle as an output light source through reducing optics, and irradiating a site of the tape, said site being capable of forming servo tracks, with the laser light transmitted through said reducing optics to form a plurality of servo track patterns in a running direction of the tape at a smaller pitch than the pitch of the optical fibers arrayed in said optical fiber bundle.
