Write control method in storage device

Abstract

Abstract PURPOSE:To increase an amount of storage of data to a medium, without requiring the provision of a file to a stored data, by using a write clock formed in response to the result of counting of compressed data outputted from a code section. CONSTITUTION:When a main scanning time of an input data D from a scanner 11 in N seconds, a data Dc is tentatively stored in a buffer 21B by taking a pickup speed of the compressed data Dc from a code section 21A as a speed to be read out entiely within the N seconds, and a counter 21C counts the number of bits of the data Dc with a counter 21C. The content of the buffer 21B and the counter 21C is transferred to a buffer 21D and a latch 21E through the line synchronism of the main scanning, the buffer 21B and the counter 21C are reset for the storage of the compressed data of the next line and the count of the compressed bit number. Through M-bit being the content of the latch 21E, a generator 21F forms a clock in M/N-bit and the content of the buffer 21D is stored in a main memory 22.
