Abstract: PROBLEM TO BE SOLVED: To improve productivity and resolution in a transfer process to duplicate disks without carrying out an injection process using a stamper by irradiating the surface of the recording layer with light to form various kinds of signal marks. SOLUTION: A sheet type substrate 10 is wound on a feeding cylinder 20 and released by the rotation of the feeding cylinder 20.
