摘要： There is provided an information storage apparatus including recording medium and a head. The recording medium has an electrode layer, a magnetic layer that is stacked on the electrode layer, and a wear-resistant thin film that is stacked on the magnetic layer. The head has a conductive probe for injecting charge to record information and sensing the charge injected into the recording medium to reproduce information in a state that the conductive probe contacts the recording medium. A magnetic medium, which is coated with a wear-resistant thin film, stores charges to record information and reproduce information using an electrostatic force. Thus, it is possible to stably store highly integrated information. Also, a probe contacts a recording medium to record and reproduce information at a high speed. Thus, sensitivity and resolution can be improved.
