| abstract | (57) [Abstract] [Purpose] To provide a composite disk capable of achieving good contact running of a magnetic head and good magnetic recording / reproducing characteristics. [Structure] The composite disc 11 comprises an optical recording layer 3 on which optical information is to be recorded, an optical recording layer protective film 4 for protecting the optical recording layer 3, and a magnetic disk on a disk-shaped transparent substrate 1. Magnetic layer 5 formed of a material or a material mainly composed of a magnetic material And a lubricating layer 7 made of silicone oil are sequentially laminated, and the maximum height Rmax of the surface roughness of the magnetic head sliding traveling surface on the surface of the magnetic layer 5 is 0.02 to 2.5 μm. And As a result, the frictional force (friction coefficient) is kept constant, the magnetic head can be satisfactorily contact-traveled, and good magnetic recording characteristics can be obtained. |
