Abstract

We present a new runlength-limited modulation technique based on the variable-length encoding principle. The code achieves minimum and maximum runlengths Tmin = 1.5 and Tmax = 4.5, respectively. Decoding is very simple and only needs an observation field of six channel bits. The new code is compared with other codes achieving Tmin = 1.5.

The ideal low- and high-frequency capacitance-voltage curves of a semiconductor(2)-insulator-semiconductor(1) (SIS) structure were first calculated with the insulator thickness, conductivity types and doping concentrations in semiconductor(1) and semiconductor(2) as parameters. The effects of fixed oxide charge and interface trap charge on the low and high frequency capacitance-voltage curves were also calculated. It was found that the fixed oxide sheet charge density with its centroid and the order estimation of the interface trap charge density with its effective type in addition to the insulator thickness, conductivity types and doping concentrations in semiconductor(1) and semiconductor(2) could be estimated from measured low and high frequency capacitance-voltage curves of an SIS structure.

The sound from a Compact Disc system encoded into data bits and modulated into channel bits is sent along the 'transmission channel' consisting of write laser - master disk - user disk - optical pick-up. The maximum information density on the disk is determined by the diameter d of the laser light spot on the disk and the 'number of data bits per light spot'. The effect of making d smaller is to greatly reduce the manufacturing tolerances for the player and the disk. The compromise adopted is d approximately equals 1 mu m, giving very small tolerances for objective disk tilt, disk thickness and defocusing.

Ideas which have origins in C. E. Shannon's work in information theory have arisen independently in a mathematical discipline called symbolic dynamics. These ideas have been refined and developed in recent years to a point where they yield general algorithms for constructing practical coding schemes with engineering applications. In this work we prove an extension of a coding theorem of B. Marcus and trace a line of mathematics from abstract topological dynamics to concrete logic network diagrams.

The binary 3PM code has at least two ZEROS between transitions, and thus has an increase in density ratio over MFM. While the original 3PM had at most 11 ZEROS between transitions, this number has been reduced to 7 by look-ahead techniques, whereby the present code word can be a function of input bits yet to come. The ability to "see into the future" enables look-ahead codes to achieve rates close to capacity with simple logic: so long as m/n≤capacity, it is possible to achieve an m-into-n code with an m and n relatively prime. Encoding is done one word at a time by observing the contents of the present code word, the previous code word, and the look-ahead region 4 bits wide, and substituting patterns not used in the basic encoding. Changes are made only in the present word and its preceding bit. Decoding is done likewise, with an observation field of 14 positions.

This paper describes a novel run-length limited code, termed 3PM. A group of three data bits is converted into six code bits which are represented by the presence or absence of signal transitions. At least two zeros are maintained between two consecutive ones, that is a minimum distance of three positions between transitions, resulting in great reduction of pulse crowding. The minimum distance is assured by a unique merging rule at the boundary of adjacent code words. This rule distinguishes the code from both fixed and variable length codes and results in very simple encoding and decoding algorithms. An actual 50% density increase has been accomplished in saturation recording by using the 3PM code in combination with other electronic techniques. The new code is used in a current ISS/Univac high density disk storage system, featuring 2500 bits/cm (6300 BPI) linear density, 10 Mbits/sec data rate, 338 MByte capacity and one bit in 10 billion raw error rate on conventional Mod-11 head/disk interface.
