According to one embodiment, a method for manufacturing a patterned media includes forming patterns of a magnetic layer having protrusions and recesses corresponding to tracks, servo zones or data zones on a substrate having a center hole, and spraying gas flow produced by diffusing a liquid gas toward the center hole of the substrate before or after forming the patterns of the magnetic layer. The database entries are representative of variable information and the template file includes data designating a first variable text area and a second variable text area. The search unit executes the search process with using the extracted keyword. A method for detecting single ventricular loss of capture in bi-ventricular pacing is also described utilizing comparison of evoked QRS complex morphology to a predefined waveform. The first circuit layer is integrated with the carrying surface and electrically connected to the light source. A method for producing a relief printing plate by using the original plate is also provided.
