Abstract
An apparatus and method are disclosed to encode binary data into trinary data. Applicants' method provides binary data, and encodes that binary data into trinary data. By 'binary data,' Applicants mean a plurality of bits, wherein each of those bits comprises a value selected from the group consisting of a first value and a second value. By 'trinary data,' Applicants mean a plurality of bits, wherein each of those bits comprises a value selected from the group consisting of a first value, a second value, and a third value. The trinary data may be stored in ROM optical disks, nano-sized indentations in a thin-film, or multi-level magnetic storage. The trinary data may be also transmitted via three light levels in an optical communications network.
