摘要

PROBLEM TO BE SOLVED: To allow a hologram recording material in an inner part to be heated without losing strength of a cartridge casing and with a simple constitution. SOLUTION: An electromagnetic induction heating body 304 is provided in the cartridge casing 301 of a cartridge type hologram recording medium 20. This is irradiated with magnetic force outputted from a magnetic force generator 400 disposed in a hologram device and heat is generated to heat the hologram recording material 302 housed in the cartridge casing 301. Thereby, the hologram recording material 302 can be heated without losing strength of the cartridge casing 301 and with a simple constitution. COPYRIGHT: (C)2007,JPO&INPIT
