Abstract
Recording, reproduction or erasing of information is performed on a recording medium having a recording layer provided on an electrode substrate. The electrode substrate has a regular periodic structure within a plane and the structure is detected through the recording layer by use of a probe electrode to determine a desired position on the recording medium.
Claims36
An information processing method, comprising the steps of:
- providing a recording medium having a recording layer on an electrode substrate having a regular periodic structure within a plane;
- determining a recording position on the periodic structure of the substrate through the recording layer by use of a first probe electrode;
- and
- performing at least one of recording, reproducing and erasing of information by use of a second probe electrode at a desired position on the recording layer corresponding to the determined recording position.
