A recording and reproducing device capable of storing video-recording and reproducing position with reference to a character string inputted at that point of time and of reproducing the recorded video data starting at a specified position by pointing the related character string. The blend is subjected to a CBN high temperaturehigh pressure process for forming a CBN product. In an effort to avoid tip damage and remain in non-contact, attractive mode during use, a setpoint just above a setpoint corresponding to a detected change in a parameter of the detector signal, such as an abrupt change in phase, may be used to operate the AFM. During runtime this statistical information is used in cases where the attachment of some phrase type of interest is ambiguous. The method and system may exclude the inaccurate weather parameters identified from a reasonable weather database.
