Abstract: An information processing apparatus includes a memory and a processor. The memory stores trace information including a string of location information which indicates locations of texts in a source code that correspond to instructions that have already been executed and which stores an execution order of the instructions. The processor detects a substring that appears a plurality of times from the string of location information included in the trace information and determines location information that belongs to a loop and an execution status of the loop. The processor associates, based on the location information that belongs to the loop, the execution status of the loop with the source code and displays the associated information.

Abstract: To provide an optical information recording medium including a pigment appropriate for high-density and high-speed optical recording by the blue laser light of 350 to 500 nm and especially around 400 nm (for example, 405 nm), enabling recording at low power, suppressing thermal affect of recording to the optical recording layer, and assuring a reflection ratio or modulation degree by the change of a refraction index n and an attenuation coefficient k; and to provide a recording method thereof. Instead of the recording based on the optical phase difference obtained by a change ?n of the refraction index n of the pigment as in the conventional method, a pigment capable of performing recording based on the change ?k of the attenuation coefficient k has been obtained. Recording may be performed mainly by the change ?k of the attenuation coefficient k.
