A high-intensity light comprising a side-emitting optoelectronic device adapted to emit light of a desired color. The microencapsulated beads are attached and embedded in the compressed cloth. It compares the temperature of a given physical storage device to a temperature threshold value of this physical storage device or compares it to an affected temperature thereof due to the variable factor generation sources, thereby moving, for data transfer, an operation position of physical storage device based on a comparison result at such time.
