Abstract: A substrate onto which a coating solution is dropped is rotated at a low speed in a first rotational mode and then after an interval of time at a high speed in a second rotational mode. At the end of the first rotational mode, the coating solution is coated to a thickness larger than a given thickness on irregularities on the substrate such as twin patterns and a global pattern, with the coating solution being coated to a thickness smaller than the given thickness between the twin patterns. Subsequently, at the start of the second rotational mode, the coating solution coated on the twin patterns and the global pattern flows into spaces between these patterns. At the end of the second rotational mode, the thickness of the coating solution on the twin patterns is almost nil, and the thickness of the coating solution on the global pattern is small in its entirety though it is somewhat large in the central area of the global pattern.

Abstract: A video signal processing apparatus and method are provided in which time base errors in the luminance and color signals of a video signal reproduced from a recording medium are compensated. Time base errors in the luminance signal are reduced by storing the luminance signal in a first memory in response to a write clock singal synchronized with the video signal and subsequently reading the luminance signal from the memory in response to a first read clock signal synchronized with a stable clock signal. Time base errors in the color signal are reduced by writing the color signal in a second memory in response to the write clock signal and subsequently reading the color signal from the second memory in response to a second read clock signal synchronized with the stable clock signal such that corresponding portions of the luminance signal and the color signal are read from the first and second memories at different respective times with a predetermined time difference therebetween.
