Summary

• "This book discusses the issues associated with the reliability of magnetic storage devices, particularly flexible media such as tapes. After a brief introduction to the physics of magnetic recording and data storage, and the basics of manufacturing magnetic media, the book turns to the production and properties of magnetic media based on polyethylene terephthalate (PET) films.
• This is followed by discussions of the viscoelastic properties of PET and advanced polymeric films, the mechanical stresses encountered by the films in actual use or storage, and the long-term properties of stressed films in storage." "This second edition has been revised throughout and includes a new chapter on ultra-thin advanced substrates."--BOOK JACKET.
