Analysis apparatus and analysis disc used for the same

摘要

An analysis apparatus capable of normally creating image data and an analysis disc used for this. Instead of using a signal which has been read in time series by pickup following a track so as to create an image by utilizing address information engraved on an optical disc, a mark ( 110 ) is recorded over the radius direction (A) of a read area ( 109 ) of the analysis disc ( 108 ) where an analysis object (B) is arranged, at least at a preceding position or a following position of the read area ( 109 ) in the rotation direction (C), so that video processing aligned according to this mark is executed, thereby executing video acquisition or a shape count with a high accuracy.
