Recording system of information recording medium

Abstract

Abstract PURPOSE:To obtain a recording system to an information recording medium which has a large recording capacity and can execute a sufficient protection for recording and reproducing, by encoding a data by an operation processing part, and recording this encoded data in a data recording part. CONSTITUTION:A card 11 is provided with an IC chip (data processing part) 16 and a laser recording part (data recording part) 17 on its surface. A CPU18 supplies a recording data stored in an RAM20 to a CPU in the IC chip 16 through an IC chip reader and writer 21. A CPU50 encodes a supplied recording data, and outputs this encoded data to the CPU18 through the IC chip reader and writer 21. The CPU18 operates a moving mechanism 33, and records the encoded data in the laser recording part 17 by a laser recording part reading recorder 22.
