A target peripheral nerve is treated by providing a real-time fluorescent image of a tissue region where the target peripheral nerve has an enhanced appearance in the fluorescent image. Each of the multiple streams of data is encoded to enable play back of the content according to a different level of quality. Gas is sprayed or jetted from inlets in the rotor to create a rotational gas flow. A thread is stitched along the first layer of preimpregnated tape. After error correction encoding of a CD-ROM is executed, encoding of the CIRC is executed to the recording data of one block.
