Patent ID: 8040712

Claim:
An information memory device, comprising: a memory medium which has a first solid material and a plurality of small sections that are provided inside of the first solid material for storing data and each of the small section contains a second material; a sender unit which irradiates an electromagnetic wave including a plurality of frequencies to the memory medium; a receiver unit which receives electromagnetic waves emitted from the plurality of small sections upon reception of the electromagnetic wave irradiated from the sender unit; and a processing unit which obtains data stored in the plurality of small sections and an address corresponding to the data from a spectrum of the electromagnetic wave received at the receiver unit, wherein the second material exhibits a resonance with at least one resonance frequency of the plurality of frequencies of the electromagnetic wave irradiated from the sender unit, the second material contains a material that exhibits at least one resonance phenomenon of nuclear magnetic resonance, electron spin resonance, ferromagnetic resonance, and anti-ferromagnetic resonance, and the first material is more prone to transmit the resonance frequency than the second material.
