METHOD OF WRITING SERVO SIGNAL ON MAGNETIC TAPE |
摘要 |
<p>A method of writing servo signals on magnetic tape which comprises making a single laser beam (15) pass through a diffraction element (14) to split it into a plurality of beams (16) traveling in prescribed directions and then making the plurality of beams (16) pass through an optical convergence system (21) to form converged beam spots on a site of a magnetic tape (1) which is capable of forming servo tracks, the magnetic tape (1) being running at a prescribed speed, to cause the site to change physically or chemically thereby forming a plurality of servo tracks (S) in the longitudinal direction of the tape simultaneously. <IMAGE></p> |
