Abstract:
1. An information recording apparatus comprising: a first encoding device which receives first information supplied through a first channel, encodes the first information, and transfers the encoded first information at a first transfer rate; a second encoding device which receives second information supplied through a second channel, encodes the second information, and transfers the encoded second information at a second transfer rate, the second information being different from the first information; a memory device which receives and memorizes the transferred first information and the transferred second information and outputs the memorized first information and the memorized second information to a recording device; the recording device which alternately receives the first information and the second information from the memory device, and alternately records the first information and the second information onto a recording medium at a recording rate; and a controlling device which controls the memory device such that the first information and the second information are memorized at different timing, and are output at different timing and at a outputting rate being corresponded to the recording rate, wherein the first encoding device and the second encoding device change the first transfer rate and the second transfer rate independently, and a sum of the first transfer rate and the second transfer rate is smaller than the recording rate, wherein the controlling device controls the memory device such that the increase and decrease of the volume of the memorized first information in the memory device and the increase and decrease of the volume of the memorized second information in the memory device are repeated respectively and alternately, wherein the controlling device further controls the memory device such that the decrease of the volume of the memorized second information in the memory is started at the same timing as the timing of the increase of the volume of the memorized first information in the memory is started, and that the decrease of the volume of the memorized first information in the memory is started at the same timing as the timing of the increase of the volume of the memorized second information in the memory is started, and wherein the controlling device further controls the memory device such that the outputting rate is faster than both the first transfer rate and the second transfer rate.
