Abstract

A recording device records the speed data as a binary number by using a first byte and a part of a second byte, and records the sampling number as a binary number by using the remaining part of the second byte when the number of digits of the sampling number is not greater than the number of bits of the remaining part of the second byte, while recording low-order digits of the sampling number as a binary number by using all the remaining part of the second byte and recording high-order digits of the sampling number and information for indicating record of the high-order digits of the sampling number by using a third byte when the number of digits of the sampling number becomes greater than the number of bits of the remaining part of the second byte.
