Abstract

A method for enhancing access to CD-ROM's and the like stored in a magazine has the steps of: loading a CD-ROM into a CD-ROM reader; reading a table of contents from the CD-ROM; storing the table of contents in a non-volatile memory device; and storing the CD-ROM at a known location within the magazine. Data on the CD-ROM can thus subsequently be read without re-reading the table of contents thereof. Necessary information from the table of contents is retrieved from the non-volatile memory device.
