ABSTRACT:
A recording apparatus having means for detecting a recordable area on a recording medium comprises the structures of measuring means capable of measuring the reflective luminous energy of a recording medium and of means for holding the recording medium, means for holding the data on the basis of the reflective luminous energy of the means for holding the recording medium and the data on the basis of the reflective luminous energy of the recording medium, which are measured by the measuring means, and means for setting by both of the data a threshold value utilized for determining the boundary between the recording medium and the means for holding the medium.
