<p>PURPOSE:To reduce the adverse effect caused by external vibration by providing a non recording region which has no projecting and recessing parts and a recording region which is located adjacent to the n'& recording region. CONSTITUTION:A tip 7 is formed at the tip of a probe 6 and a recording is performed by the tip 7. The surface of a recording medium 8 is divided into two kinds of regions 9 and 10. The region 9 is a non recording region in which no recording is made by STM and the region 10 is a recording region. The surface of the medium 8 is divided into the two kinds of regions in the direction of the recording and these regions are alternatively placed. In the region 9, no recording is done and an STM current is detected. In the region 10, address information of signals or information signals themselves are recorded. If a grinding is done to this surface so that the coarseness of the surface is kept less than 1nm, the probe is well controlled even though an STM current is discretely detected by taking the sampling frequency to be larger than the spatial frequency band of the substrate waviness.</p> |
