Title:
INFORMATION RECORDING/REPRODUCING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/029607
Kind Code:
A1
Abstract:
An information recording/reproducing device is provided with a recording layer and a driving section. The recording layer has a first layer which contains a first compound. The first compound contains a mixed crystal of a first oxide containing a first metal element and a second oxide which has a crystal structure identical to that of the first oxide and contains a second metal element different from the first metal element. The driving section records information by changing the state of the recording layer by at least applying a voltage to the recording layer or carrying a current to the recording layer. The composition ratio of the first metal element or the second metal element with a smaller ion radius is a threshold value of infiltration of an lattice formed by ions of the first metal element and the ions of the second metal element or higher, based on the crystal structure.
