Defect and maintenance detection for an image capture device capable of distinguishing between a defect in the ICD and one on the imaged object. The front panel and the rear panel are faced with each other, and peripheries thereof are sealed to form a discharge space therebetween. According to a different feature, the control portion moves the head to a position adjacent a portion of a surface on the storage medium, waits while moving the head relative to the surface, and then moves the head to another position adjacent a different portion of the surface. By adjusting the values of x and y the adhesion underlayer contributes to such qualities of the protective bilayer as stress compensation, chemical and mechanical stability and low electrical conductivity. The data obtained by each of the two read commands is compared, and in cases where a difference is identified between the two data, it is determined that an error has been detected and corrected by the ECC.
