Optical information recording and reproducing apparatus

An optical information recording and reproducing apparatus for performing the operation of recording and reproducing said optical information on recording medium by radiating light from the tip end of a probe comprising:

• a moving apparatus for periodically moving the radiating position of said light in a direction perpendicular to the direction of the data row arrangement on said optical information recording medium;
• and
• a signal taking-out apparatus for acquiring distance signal in relation to the distance between the tip end of said probe for radiating said light and the surface of said optical information recording medium from reflected light and transmitted-light in said light in relation to said periodical movement.

A method of performing the operation of recording and reproducing optical information on recording medium by radiating light from the tip end of a probe comprising the steps of:

• periodically moving the radiating position of said light by use of a moving apparatus in a direction perpendicular to the direction of the data row arrangement on said optical information recording medium;
• and
• acquiring tracking error signal on said radiating position from reflected light and transmitted light in said light in relation to said periodical movement by use of a signal taking-out apparatus.
