Abstract

PURPOSE:To increase the readout efficiency of sequential data, by adding and recording a specific code representing the end of data to a specific address in record unit and checking the data of the specific address. CONSTITUTION:A sequential data is sequentially arranged to a plurality of record units taking the data length of the 1st record as M, and the final address of each record is prepared as an area to store a specific code Z representing the end of data, and the specific code Z is added to the final address in the final record unit including the final data. A code representing ''not the end of data'', e.g., Q is added to each final address of the remaining record units. Thus, the end of data can immediately be discriminated by checking the data of the specific address. Thus, the readout efficiency of sequential data is increased.
