How to digitize records from 100 years ago

The Internet Archive, a non-profit organization that stores all information such as websites, books, and music, is conducting the Great 78 Project, which digitizes and stores SP records, which appeared early among records. How the hell is this project digitizing SP records?

The Internet Archive stores SP records in one box of every 80 in an appropriately temperature-controlled warehouse. Wear nitrile gloves when handling SP records. In order to digitize the SP record, the barcode on the SP record is first read and registered in the database. Next, set the device that records the SP record and add distilled water to the SP record. Next, absorb the moisture with an aspirator.

Record cleaning equipment must be checked daily. Before cleaning the SP record, distilled water is colorless and transparent, but after cleaning the SP record, it contains dust and turns black. When the SP record cleaning is complete, take a picture of the surface. Next, while viewing the taken picture, the SP record information is registered in the database.

Finally, after recording the contents of the SP record, digitization is completed. According to the Internet Archive, SP records differ in record needles suitable for playback by stuff. Therefore, the Internet Archive records the contents of SP records using a dedicated recorder equipped with four types of record needles.

Existing SP records are quite fragile, but the Internet Archive uses diamond record needles that can play music with less than 10% of the power of steel needles used in earlier times. In addition, the archived SP record sound source is publicly available on the Internet Archive website and can be freely listened to. Related information can be found here.



Through the monthly AHC PC and HowPC magazine era, he has watched 'technology age' in online IT media such as ZDNet, electronic newspaper Internet manager, editor of Consumer Journal Ivers, TechHolic publisher, and editor of Venture Square. I am curious about this market that is still full of vitality.
