There are many audio recordings of Japanese in both Japan and abroad, stored on recording media such as magnetic tapes and records, which are generally no longer used today. The total amount of material would be equivalent to decades of playback time. It is desirable that these should be stored as digital data, with their contents transcribed and made public, for linguistic research and many other purposes. However, the conversion process takes a great deal of time and is very costly at each phase. Therefore, it is difficult to convert all the material with current technology. Additionally, it is necessary to select an appropriate reproduction system based on the type of recording medium. In this paper, I discuss the results of examining a method of high-speed reading of audio information - that does not depend on the type of magnetic tape — from a huge number of analog recording media made in the past.
