摘要：
An anti-reflection coating layer is formed on the surface portion of a recording medium. This enables to obtain a margin for the air gap thickness change when recording/reproducing an information signal using the “near-field technique” as well as minimize a data loss caused by a collision. Furthermore, the present invention provides a film configuration which can easily be produced.
