  • Data storage method and data storage device
    Patent number: 7331025
    Abstract: In a data storage method and device, input data having a pattern are divided into a plurality of fields. A first number of rectangles contained in each field of an original image of the pattern is calculated by dividing the field of the original image into one or plurality of rectangles. A second number of rectangles contained in each field of an inverted image of the pattern is calculated by dividing the field of the inverted image into one or plurality of rectangles. One of pattern data of the original image and pattern data of the inverted image which has a smaller number of rectangles is selected by comparing the first number of the rectangles in the original image with the second number of the rectangles in the inverted image. The pattern data selected for each field are stored in a recording medium.
