摘要： An optical recording medium having a disconnected land and/or a groove thereby forming a control signal portion. The control signal portion may have therein a clock signal. The disconnect is formed by wobbling a laser beam while applying the laser beam to a photoresist layer formed on an original glass disk to cut circumferential grooves therein. The beam is wobbled in the radial direction to form a disconnect in the circumferential groove and simultaneously therewith a mark to disconnect a land between grooves.

摘要： A mastering method for making a high recording density optical disk is disclosed, in which a substrate with a photosensitive material layer is selectively exposed to a focused laser light having a predetermined power representing information to be recorded. The laser power is such that the exposed width at the top surface of the photosensitive material layer is larger than the exposed width at the bottom surface of the photosensitive material layer. After the development of the layer, the remaining photosensitive material layer is used as an etching mask for the substrate to form pits in the substrate.
