摘要： A code conversion method and apparatus is provided for scrambling and modulating data. The method and apparatus includes scrambling an input main data unit based on any of plural types of pseudo-random number sequences, and modulating the scrambled main data unit based on any of plural types of modulation data. An output main data unit is produced from the modulated main data unit, and a calculated value representing a difference between a number of 0 bits and a number of 1 bits included in the output main data unit is obtained. Any of the modulation data is then selected dependent upon the calculated value. The method and apparatus further includes determining whether or not a variation of the calculated value has exceeded a predetermined threshold, newly selecting another pseudo-random number sequence used for the step of scrambling if it is determined that the variation of the calculated value has exceeded the predetermined threshold value, and re-scrambling the input main data unit based on the newly selected pseudo-random number sequence.

摘要： In an optical disc, an ID field contains a plurality of address information, and is preliminarily recorded in convex and concave signals, and is composed of two sets offset by about 1/2 track pitch toward the internal or external track direction adjacent to the guide track, an information recording field is composed of grooves and lands oscillating at a single frequency in the radial direction, and the grooves and lands alternate in every revolution of the guide track. When w bits of information are included in one period of oscillation, an information unrecorded field between the ID field and information recording field is arranged to have a length of w/10 bits or more and/or w bits or less, and therefore, when recording continuous information data such as video data, it is possible to record continuously by generating a clock securely from the oscillating signal, and moreover, the format efficiency is improved, so that a format of a larger capacity is achieved.

摘要： A developing process for obtaining a resist pattern on a semiconductor wafer includes puddling a developer on a wafer and holding a wafer inclined at a predetermined tilt angle in the puddled condition and repeating alternately stoppage and slow rotation plural times. This can make the central pattern width narrower selectively simply by apparatus adjustment, in case where, otherwise the pattern width of a wafer's central portion becomes wide, thereby achieving an increased pattern uniformity of the wafer and serve as improving the performances.

摘要： After a silicon wafer is held horizontally such that a surface thereof coated with a photoresist faces upwardly, the surface of the silicon wafer is supplied with a cleaning liquid to form a puddle thereof before a developing liquid is supplied. After the puddle of the cleaning liquid is formed, the silicon wafer starts to be rotated and the developing liquid starts to be supplied to the surface of the silicon wafer. The developing liquid is supplied to the surface of the silicon wafer with the puddle of the cleaning liquid being formed thereon. Alternatively, developing liquid is supplied to the surface of the silicon wafer which is being supplied with cleaning liquid while the silicon wafer is being rotated.
