Abstract

An information processor comprises a plurality of probes disposed so as to face to a recording medium containing an information, and a plurality of elastic members such as cantilevers supporting the respective probes. The processor reads the information by detecting each displacement of the elastic members. For the detection of displacement, the processor has an optical system for radiating a scanning light beam to the elastic members together with an optical system for detecting a reflected light from the elastic members, or alternatively has a means for detecting each displacement individually such as optically integrated optical members or piezoelectric layers provided to the elastic members.
