According to one embodiment, a semiconductor memory device includes a memory which comprises an area accessible from outside and a confidential information area storing confidential information and a set flag. A controller reads the flag from the memory when instructed to erase data in the confidential information area, determines whether the flag is set, erases data in the confidential information area when the flag is clear, and abandons process requested by the data erase instruction when the flag is set. An authenticator uses data in the confidential information area to execute operation for authentication.

According to this invention, a fingerprint sensor is mounted for fingerprint collation, and a movable protection unit which coverts the fingerprint sensor is arranged. In fingerprint authentication, the protection unit moves to expose the fingerprint sensor. Along with movement, the apparatus is powered on and activated, and the fingerprint sensor also operates to perform collation processing. The protection unit which covers the fingerprint sensor in normal use is formed by a member capable of handwriting input. This arrangement provides an information terminal apparatus which has a collation function and enables handwriting input.

A magnetic recording medium and a manufacturing method therefore includes a protective film, a nonmagnetic substrate, a nonmagnetic base layer, a nonmagnetic intermediate layer, a magnetic layer, and a liquid lubricant layer. The nonmagnetic base layer has a body-centered cubic structure and a (200) plane including a crystal-orientation parallel with a surface of the protective film. The nonmagnetic intermediate layer has a hexagonal close-packed structure and a (110) plane including a crystal-orientation parallel with the surface of the protective film. The magnetic layer has a granular structure including hexagonal close-packed ferromagnetic crystal grains and oxide-based nonmagnetic grain boundaries surrounding the ferromagnetic crystal grains. The nonmagnetic base layer, the nonmagnetic intermediate layer, the magnetic layer, the protective film, and the liquid lubricant layer are sequentially stacked on the nonmagnetic substrate.

摘要:
A method of manufacturing a magnetic recording medium facilitates preventing a film inflation from occurring in an environmental condition range between −40° C. and 80° C. and an 80% relative humidity. The magnetic recording medium includes a plastic substrate and an undercoating layer on the plastic substrate. The undercoating layer is provided with a columnar structure, which prevents water (moisture) between the plastic substrate and the undercoating layer from aggregating and, therefore, the film inflation from occurring.
