Information recording/reproducing apparatus having fuzzy operating unit

A method of performing at least one of recording of information on and reproducing information from a recording medium having a track groove by using a probe, said method comprising the steps of:

• effecting a relative movement between said probe and the recording medium in a medium surface direction;
• applying a voltage between said probe and the recording medium;
• detecting physical information generated upon application of the voltage;
• detecting an edge position of the track groove from the detected physical information;
• generating a signal indicating a relative deviation amount between said relative movement and said edge position using fuzzy deduction when edge position is detected;
• and
• correcting a relative deviation between said relative movement and said edge position on the basis of said signal indicating said relative deviation amount.

A method of performing at least one of recording of information on and reproduction of information from a recording medium using a probe while effecting relative movement between the probe and the recorded medium having a track groove with moving means, said method comprising the steps of:

• supplying a predetermined drive signal to the moving means so as to effect a predetermined relative movement between the probe and the recording medium in a medium surface direction;
• detecting physical information generated by the interaction between the probe and the recording medium;
• detecting an edge position of the track groove from the detected physical information;
• holding the drive signal supplied to the moving means when the edge position is detected;
• and
• generating a correction value for correcting the predetermined relative movement using the held drive signal and fuzzy deduction.

An information recording or reproducing apparatus for performing at least one of recording of information on and reproduction of information from a recording medium having a track groove by using a probe, the apparatus comprising:

• a probe;
• moving means for effecting relative movement between said probe and the recording medium in a medium surface direction;
• driving means for supplying a predetermined drive signal to said moving means so as to effect a predetermined relative movement between said probe and the recording medium;
• detection means for detecting physical information generated by the interaction between said probe and the recording medium;
• means for detecting an edge position of the track groove from the detected physical information;
• means for holding a drive signal supplied to said moving means when said edge detecting means detects the edge position;
• and
• means for generating a correction value for correcting the predetermined relative movement using the held drive signal and fuzzy deduction.
