Magnetic recording medium, its recording/reproducing method and information processor which uses the medium and method |
| abstract |
A disklike magnetic recording medium having a magnetic layer containing a magnetic substance on a non-magnetic support, and a layer containing a pigment whose optical characteristics are changed by the irradiation of energy beam and interposed between the non-magnetic support and the magnetic layer. A continuous servo signal is recorded on the concentric tracks on the pigment-containing layer in accordance with variation of the optical characteristics of the pigment. This medium can be manufactured at a low cost, and has a large recordable area. Accurate tracking can be done by a single detector. |
