Investigation on Filmon Sound Belt
The Filmon Sound Belt is a special storage medium (a kind of record) developed in prewar Japan. The shape is an endless tape made of synthetic resin (approximately 13 m long), and it is said that the tape can record sound for up to 36 minutes. The Department of Intangible Cultural Heritage owns five such sound belts. Since a special player is needed to play them and very few players now remain, it has not been possible to even check what is recorded on them up to now.
Since last year, the Department has been researching the Filmon sound Belts jointly with the Theatre Museum of Waseda University (Collaborative Research Center for Theatre and Film Arts). The Theatre Museum stores the players in a playable state, so digitizing the sounds played back by the players is also included in the investigation plan.
At present, we have confirmed there are a total of more than 100 sound belts in existence when including those stored in the Department of Intangible Cultural Heritage and Theatre Museum and those owned privately. Unfortunately, quite a few of these sound belts are hard to play back since they have deteriorated noticeably through age, but we are now working to obtain playback sound from as many belts as possible.
