PENETRATING TYPE OPTICAL DISK

摘要

PURPOSE: A transparent optical disk is provided to effectively rapidly and effectively search stored content by scanning and sensing the whole optical disk at once. CONSTITUTION: A transparent optical disk is comprised of a main disk(100) of a wafer type and penetrates light from one surface to other surface per a sector. A main disk includes holes(10) which is penetrated from one surface to the other surface. A body of the main disk is comprised of a non-transparent plastic material. The holes are formed into a rectangular. The main disk is comprised of a transparent plastic material. A sub layer which is a non-transparent plastic material which has the holes is combined to one side of the main disk.
