ABSTRACT:
An image information filing apparatus includes a data compressing circuit for compressing line image information corresponding to each scanning line to decrease the redundancy of the image information and a circuit section for adding line sync code and EOL and CRC codes to the head and end of the line image information, respectively. When the line sync code is MFM-modulated together with the line image information, one pulse is removed from the modulated pulses corresponding to the line sync code. The line image information are separated from each other by the detection of the line sync code with the missing pulse.
