In a music information database, music information where music pieces and impression words representing impressions of the music pieces and usable as search words when any of the music pieces is to be searched for is registered for a plurality of music pieces. Information collection section collects, from among various information being provided by information source sites, information usable as music-piece-related search words. Registration section registers the words usable as music-piece-related search words, collected by the information collection section, into the database in association with particular music pieces. In this way, it is possible to construct a music information database which permits a music information search therethrough using impression words representing impressions of a music piece, at low cost without taking much time and labor.

Database constructing apparatus and method

A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost thereof.
