Traceability, Reproducibility, Compatibility - Quality Control Elements in Audio Information Transfer   

In transfer from one medium to another or one format to another, the target format may be able to hold more information or less information than the original. According to the purpose of the transfer, a selection offeatures may be made as a minimum requirement for transfer. Awareness of Traceability, Reproducibility and Compatibility will ensure the fulfilment of these requirements. The dedicated transfer station approach using calibrated equipment is contrasted with the use of diagnostic signals for use with transfer stations of any standard. The advantages and disadvantages of the respective approaches are mentioed, in particular as regards long term storage. The background for creating diagnostic signalsfor transfer of mechanical recordings is discussed in depth.

Up-To-Date Replay Facilities for Obsolete Mechanical Recording Formats   

Obsolete mechanical formats forma major part of archives’ holdings, Once a format has passed into obsolescence, there is virtually no commercial development in replay facilities, and the system as such dies. The paper discusses the fundamental principles of mechanical recording and replay as well as the latest constructions for replaying historical discs and cylinders - commercial and non-commercial. An Aaliendum gives simple instructions to the archive having only an occasional need to replay historical formats.
