A method, apparatus, and system perform fast sector identification and base station synchronization. The base station transmits information in primary and secondary control channels to the remote station. The remote station performs synchronization using information in the primary and secondary control channels. A group of identification codes corresponding to the sector is determined using information in the secondary control channel. If this does not result in identification of the sector, an identification code corresponding to the sector is determined from information in the primary control channel. If this does not result in identification of the sector, the sector is identified based on information multiplied with symbols, e.g., pilot symbols, in the primary control channel, without having to decode the BCCH.

A driving apparatus for a recording medium, wherein said recording medium is accommodated within a case, said case is adapted so that slanting sections are constructed at both end sections in a front end section that is on a side of insertion into said driving apparatus, in said driving apparatus, stoppers for preventing error insertion are provided in correspondence with said slanting sections of said case, and further, in case that said case is inserted into said driving apparatus, when said both end sections of said stoppers are subject to force opposed to elastic rebound force by means of said slanting sections at said both end sections in said front end section of said case, and are displaced, grooves for guiding displacement of said both end sections of said stoppers are provided in a direction intersecting to a direction of insertion of said case into said driving apparatus, and said stoppers are formed of an elastic rebound member, and said elastic rebound stoppers are generally formed in a shape of a letter V, and said both end sections of said stoppers are placed within said grooves so as to be displaced in an upper or a lower direction to a surface of said case to be inserted into said driving apparatus, and said stoppers are constructed so that, in case that said case is inserted into said driving apparatus, s
