Abstract: A system for encoding digital data with an M-ary (d,k) code to provide multi-level coded data where M>2 comprises an M-ary (d,k) encoder for accepting digital input data. The M-ary (d,k) coder (304) encodes the digital input data to produce a plurality of code symbols, where each code symbol is at one of M levels and each pair of non-zero code symbols is separated by at least d but no more than k zeros. A waveform encoder (308) converts the code symbols into waveform signal amplitudes compatible with a multi-level channel. Each waveform signal amplitude is generated by modulo M addition of a current code symbol with a previous waveform signal amplitude. A specific M=7 (1,3) code provides high density recording to a multi-level storage medium. The M=7 (1,3) encoder is implemented using a three-state encoder (304) and a modulo seven waveform encoder (308).

Abstract: An erasable optical disk drive system is disclosed which utilizes an electron trapping media (14) coated on the disk surface (10) to store data in the form of light energy and which utilizes three laser beams (50, 52, 54), each having a wavelength range distinct from each other as well as distinct from the wavelength range of the emission produced by the impingement of the read laser onto the electron trapping media. Data is written onto the disk, which is contained in a light-tight contamination-free environment, using a visible light laser beam. Data is read from the disk and the disk is erased by using a near infrared light laser beam (52). The focus and tracking functions of the disk drive system are accomplished by using a laser beam (54) having yet another range of wavelengths, which are greater than those of the visible light laser beam and those of the photon emission from the electron trapping optical memory media, but less than those of the read/erase laser.
