Inventor: TAKI KAZUYA
IPC: G11B7/26
Filed: 1992-02-18
Abstract: PURPOSE:To provide a mask for exposure ensuring easy alignment and high productivity and used to produce an optical recording medium giving a push-pull signal and a preformat signal with sufficiently high intensity by forming a reflecting material which generates the preformat signal at a position farther from a recording layer than a guide film.

While a magnetic tape is moved at a fixed speed, a control signal is detected from a controlling head 15, and the rotation is stopped. In the meantime, reproduction video signals are inputted to an input terminal 35, and inputted to a digital phase period measuring circuit 33, and the speed of rotation of the cylinder motor 1 is corrected.
