Disclosed is a disk drive apparatus which has a manual search function with improved operability. Upon manual search for information TNO(n+1) recorded on the outer periphery of a information write/read medium to information TNO(n) recorded on the inner periphery, there may be an gap (no sound) portion in the information between the outer and inner peripheries. In this case, the information is searched by the front-end position Pb on the outer periphery. Thereafter, no search is performed on the gap (no sound) portion through skipping from the front-end position Pb to the terminal end position Pc of the information TNO(n). Thus, only necessary information is continuously searched upon the manual search without searching the gap (no sound) portion which is not necessary for the user. Thus, the user is provided with improved operability.
