Abstract:
A recording medium including a perpendicular magnetic recording layer and a laminated SUL formed on a substrate is provided. The SUL includes an antiferromagnetic layer interposed between laminated structures including a magnetic layer, a non-magnetic layer and a magnetic layer. The layers may each have a thickness of 20 nm or less and the layers below the antiferromagnetic layer may be thinner than the layers on the antiferromagnetic layer. The laminated structures formed on and below the antiferromagnetic layer have unidirectional magnetic anisotropies set in the opposite radial direction to each other by an exchange bias. As a result, media magnetic domain noise can be diminished.

Abstract:
Disclosed is the auger in an ice bin mounted in a refrigerator, and the like. The auger in the ice bin is configured to rotate a plurality of augers having spiral-shaped transfer blades and to dispose ice in each space between the transfer blades of the auger for transfer. Accordingly, a certain amount of ice can always be discharged without simultaneously discharging a great amount of ice, and a user may select the number of ice, thus to diversity functions of an ice dispenser. In addition, since the auger is made of a flexible material, the ice can be prevented from being crushed during transfer, thereby enhancing the reliability of the ice dispenser.
Abstract:
A paper guide device which guides a sheet of paper fed to a nip between an image belt and a transfer roller and an image forming apparatus including the same. The paper guide device includes a first convey guiding unit arranged within a predetermined space from an image belt to firstly guiding the paper to a nip between the image belt and a transfer roller. A second convey guiding unit is arranged on the first convey guiding unit to contact the image belt to secondly guide the paper to the nip without contacting the image belt. The device accurately guides the paper to the nip without contacting the image transfer belt.
