Provided is an optical fiber assembly with which flexibility in the vicinity of an alignment member can be maintained, as well as a method for manufacturing this optical fiber assembly, and an optical probe which uses this optical fiber assembly. In inspection or recording of a magnetic disc, which rotates the magnetic disc, a servo pattern is written into a servo pattern region of the magnetic disc by a write-in element of a magnetic head, and is read by a read-in element of the magnetic head. A list of concepts and associated scores is received. The FP filter and the WBGs are respectively tuned to transmit and reflect a selected wavelength.
