The method of controlling laser power of an optical disk player, in which liner velocity of writing data is accelerated, by stages, toward an outer edge of an optical disk, is characterized in that a laser power for writing data is changed when the liner velocity is changed. A catheter is disclosed that includes a small diameter disk loaded monopole antenna surrounded by fusion material having a high heat of fusion and a melting point preferably at or near body temperature. The formatting may also include formatting one or more transmission and allowing the terminal to select the transmission having a matchingcompatible format. The at least one first polymer layer alternates with the at least one second polymer layer, respectively, to form a pair of distributed Bragg reflecting mirrors.
