摘要： A method for recording information on a rewritable recording medium includes recording synchronizing signal information in a synchronizing signal portion on the medium, recording data information in a data portion of the medium after the synchronizing signal portion by forming marks in the data portion, and substantially randomly inverting the marks and spaces between the marks each time the information is recorded. The marks for particular areas of the medium are different in a physical property from other areas of the medium and data information is recorded in association with both ends of each of the marks. Upon rewriting of at least the recorded synchronizing signal information, a length of the synchronizing signal portion changes and a start position of the synchronizing signal portion changes, and wherein a change of the synchronizing signal information start position is smaller than a change of the length of the synchronizing signal portion.

摘要： In size measurement of a semiconductor device, profiles of a pattern formed in a resist process are determined through an exposure/development simulation in respect of individual different combinations of exposure values and focus values to form a profile matrix and scattered light intensity distributions corresponding to the individual profiles are determined through calculation to form a scattered light library, thereby forming a profile library consisting of the profile matrix and scattered light library. A scattered light intensity distribution of an actually measured pattern is compared with the scattered light intensity distributions of the scattered light library and a profile of profile matrix corresponding to a scattered light intensity distribution of scattered light library having the highest coincidence is determined as a three-dimensional shape of the actually measured pattern.
