Abstract
PURPOSE:To read the information recorded at a recording medium at a high speed by winding and holding the recording medium able to be read by an optical means to a rotary drum and rotating and driving this. CONSTITUTION:When a sheet-shaped recording medium 11 is cylindrically wound with a surface having the recording information able to be read optically outside, recording information is arranged so as to be continuous in the peripheral direction on a cylinder surface. The recording medium 11 is wound and held on a rotary drum 14, for example, by the means such as a guide line, and rotated together with the rotating and driving of the rotary drum 14. For example, a line sensor 13 goes straight on so as to proceed only by the width of a signal bit group per circumference of the rotary drum 14 in the shaft direction of the rotary drum 14. Thus, the whole surface of the recording information is scanned, and the recording information can be read successively continuously and at a high speed.
