PROBLEM TO BE SOLVED: To provide an information recording apparatus, which selects a fittest data coding method on the basis of a utilization time required by a user and a residual battery power, reduces the battery power to be consumed for recording pictures and voices, reserves the utilization time requested by the user, and records the pictures and the voices with high fidelity as possible during the utilization time. SOLUTION: An information recording apparatus estimates a residual battery power on the basis of an output voltage and a temperature of a battery when a user sets a utilization request time frame (time frame for recording pictures and voices) from a tablet 11 and a keyboard 13. The recording apparatus computes a usable current rating that can be consumed by a unit time on the basis of the utilization request time frame and the residual battery power. The apparatus selects a data coding method that can be implemented within the utilization request time frame by computing the usable current value and a memory usage with a help of a plurality of coding methods recorded in a ROM 2 as a table with priorities.
