Our studio specialises in the preservation of magnetic audiotape, supporting our clients with handling, cleaning and storage of magnetic audiotapes to HQ archival WAV or FLAC digital files that comply with The National Archives Specifications. 

Audio samples are from The Sir Walter Hayes Collection we were commissioned to archive.  These can be viewed

  • Preservation Copy:  Our technicians create high quality duplicates of the original record.  Output will have a high sampling rate, high bitrate, no compression and in a open or non-proprietary format. This way, if the original record deteriorates beyond use the preservation copy will be able to take its place. A preservation copy will last for years or decades.

  • Access Copy:  This is a well supported digital MP3 copy that you can play back easily.

Structure of Magnetic Tape: Our studio specialises in converting tape using iron oxide on polyester base film. This base film has been used since the mid-sixties as a replacement for acetate bases film that was prone to chemical instability.

Sticky-shed syndrome:   Unfortunately changes made by manufacturers meant a chemical  instability causing a 'binder' on the tape started breaking down, absorbing water as a result.  This caused the tape coatings to become sticky and shed oxide onto the tape recorders heads, guides, rollers, and capstans. This is commonly called sticky-shed syndrome.  To resolve this, we heat the tapes at a very low temperature in order drive the water out of the binders.

Handling:  Our trained archive specialists handle all orders with a white glove approach. Audio reels are handled by the center hub area or by the outer edges of the reel flanges, ensuring that the actual tape is not touched. Cassettes are handled by the existing outer plastic case and that fingers not be placed anywhere inside the cassette mechanism.

Storage:  Storage is extremely important. The National Archives recommends that any tapes needing preservation should be stored between 65–70 °F (18–21 °C) at 45-50% relative humidity.  Cold weather conditions below 46 °F (8 °C), means the tape lubricant can separate from the base, ruining the recording. The most important thing is to keep conditions consistent once desirable conditions are achieved.
