In a light reflection pattern formed on a bottom surface of a light conductive plate, an inclined surface of grooves positioned at a predetermined distance or farther from a lamp includes a non-flat portion whose inclination angle varies gradually. One outer layer functions as the primary adhesive layer for adhering the patch to the host. Each portion of the media case forms a recess preferably configured to securely hold a plurality of media storage device of different size and type. However, spaces between each of other coil parts are sufficiently kept apart. Accordingly, the number of instructions that can be parallel-processed in a processor may be increased. As the invention can be extensively applied to a myriad of miniaturizing industries, it can solve all the drawbacks of the prior art manufacturing process and miniaturization.
