Abstract: A threaded reflective cord comprises a jacket and an inner cord; the inner cord comprising more than two stranded wires twisted helically and an cladding covered on the wire strands; wherein the cladding having an inner side thereof is embedded into a helical gap which is formed when the stranded wires are twisted helically; the helical gap forms and keeps an inward pre-tightening force on the stranded wires, the jacket and the inner cord having a reflective tape disposed therebetween, the reflective tape being spirally wounded on an outer side of the cladding; the jacket having an inner side thereof is coated on the cladding and embedded into a helical groove which is formed when the reflective tape is spirally wounded on the outer side of the cladding; the flexural resistance of the threaded reflective cord and the reflection performance are enhanced.

Abstract: A semiconductor recording medium recording and/or reproducing apparatus includes: a medium holder that has a medium housing unit in which a semiconductor recording medium is detachably housed; an exterior case that has a medium entrance through which the semiconductor recording medium is inserted and ejected, and in which the medium holder is housed in a state where the medium housing unit is opposed to the medium entrance; an openable and closeable cover that opens and closes the medium entrance; a heat sink that is contactable with the semiconductor recording medium housed in the medium housing unit; and a heat sink moving unit that moves the heat sink in cooperation with an opening and closing operation of the openable and closeable cover.
