a recording layer(14) which data is recorded in; a guide/mask layer(30) in the form of continuous belt between a substrate(10) and an intermediate layer(12); and a number of circular holes(40) aligned in the guide/mask layer(30). The guide/mask layer(30) is formed by depositing a metal such as Al, Cu, Au, Ti, Zn and the circular holes are formed by wet or plasma etching the guide/mask layer(30). |
