Abstract: A biometrics authentication device utilizes biometrics information and performs individual authentication enables secure modification of authorization details for an authorized agent other than the principal. A verification device verifies biometrics information registered on an IC card against biometrics information detected by a detection unit. When results in satisfactory biometrics authentication, modification of authorization details of an authorized agent, registered on the IC card, is permitted. Authorization details for an authorized agent can be securely modified on a card on which biometrics information for the principal and the authorized agent is registered.

Abstract: A trailing shield is provided on a trailing side of a magnetic pole with a non-magnetic gap layer in between, and an intermediate layer having negative uniaxial magnetocrystalline anisotropy is provided between the non-magnetic gap layer and the trailing shield. The intermediate layer has a magnetic property in which an easy axis of magnetization is provided in an in-plane direction and thus magnetization is likely to occur in that direction, whereas a difficult axis of magnetization is provided in a direction intersecting the in-plane direction and thus magnetization is less likely to occur in that direction. Accordingly, magnetic flux becomes difficult to excessively flow from the magnetic pole into the trailing shield.
