Abstract: A communication terminal having a touch panel and a method for determining a touch coordinate therein are provided. The method includes setting one of a plurality of temporary coordinates of a touch position as a touch coordinate when a touch occurs on the touch panel, extracting a temporary coordinate at a position closest to the set touch coordinate from a plurality of temporary coordinates in a touch region on a drag path when a drag occurs from the touch position and updating the set touch coordinate using the extracted temporary coordinate. Accordingly, an unintentional change of the screen can be prevented on the touch panel of the communication terminal by preventing the communication terminal from too sensitively reacting to a minimal touch occurring on the touch pad.

Abstract: Provided is a perpendicular magnetic recording medium. The perpendicular magnetic recording medium includes: a lower structure; and a recording layer formed on the lower structure, wherein the recording layer has a balancing force 2πMr2/K1 of 0.5 or less and a factor 4πMr/Hc of 0.8 or less where Mr denotes a remnant magnetization, K1 denotes a perpendicular magnetic anisotropy energy constant, and Hc denotes a coercive force. Accordingly, even though grain boundaries between grains that constitute the recording layer are somewhat non-uniform in width, the grains can have almost the same nucleation field. As a result, the perpendicular magnetic recording medium can ensure high recording density and stability of recorded information.

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.
