ABSTRACT:
Information storage media, such as cassette tapes or laser discs adapted to be read by machines, such as cassette tape players or compact disc players, has some information stored thereon adapted to be played back at a first speed and other information stored thereon adapted to be played back at a second speed. The storage or playback characteristic of the information on the media will generally vary with the speed at which the information is adapted to be read and the information is divided between the two speeds based on such characteristics. The media may advantageously be used to provide full text readings of magazines, newspapers, books, etc., and to provide indexing for such full text readings. The full text readings are broken into separate informational items, such as the individual magazine or newspaper articles or book chapters, which are stored on the media to be read back at a slow speed while individual summaries of the separate information items are stored to be read back at a faster speed. The informational items and their summaries are arranged on the media so that an informational item may be accessed at the completion of the summary of such item.
