A pad for controlling the state of contact or flying of a slider with or to an information-recording medium and a probe for exciting near-field light having a small spot size are mounted on the slider and the pad is near to the probe. Semiconductor laser light focused by an objective lens is converted into near-field light having a small spot size near the top of the probe for exciting near-field light. The slider travels at a height of several tens nm to a recording medium substrate and information is recorded or read out on or from the information-recording medium formed on the recording medium substrate.
