An optical information recording and reproducing apparatus is provided for recording and/or reproducing information on an optical disc including a recording layer in which information can be recorded at recording positions each located at a different distance from a surface of the optical disc. The optical information recording and reproducing apparatus includes: a light source; and an objective lens which can converge the light flux from the light source onto one of the recording positions at a predetermined depth in the recording layer for recording information on the optical disc. When information to be recorded is recorded on one of the recording positions at a predetermined depth in the recording layer, the optical information recording and reproducing apparatus records information about the predetermined depth on one of the plurality of recording positions at the predetermined depth, with the information to be recorded.

Optical information recording and reproducing apparatus

An apparatus for controlling a recording device includes a first input section for inputting image information items with respect to an object, and a second input section for inputting a change signal representing a change of the object. A first memory stores a plurality of the image information items inputted by the first input section, and a control section selects at least one of the image information items stored in the first memory and for controlling the recording device to record the at least one selected image information item on a recording sheet, responsive to the input of the change signal by the second input section.
