Title: Information recording disk and its recording method
Inventor: NAGAI TADAO
IPC: G11B7/004
Filed: 1985-10-16
Abstract: PURPOSE:To prevent the mixture of noises by forming a guide track as a train of intermittent bits and also forming the bits of two adjacent guide tracks alternately in the radius direction. CONSTITUTION:A guide track is formed in the form of a train of intermittent prebits 3 and a center hole 4 is drilled to a disk 1 together with a label part 5 formed around the hole 4. The prebits 3 of two guide tracks adjacent to each other centering on an information signal recording track are set alternately in the radius direction of the disk 1. Furthermore the length of the prebit 3 is set equal to a single horizontal scan period of a video signal for example. Thus, the guide track reproduction signal of a primary light beam produces a tracking error signal. Then, the mixture of noises can be avoided into a screen.
