Abstract

With the advent of the new 120 mm optical media in block type formats of Magneto-Optic (MO), Write Once Read Many (WORM), Phase Change (PE), etc., a means of informing the user as to the type of media being used is important to prevent misuse of the media or user frustration. This is done by adding an audio track that informs the user of the type and use of the media. This idea allows the user to instantly and easily detect that the wrong media has been placed in a CD or CD-ROM drive.

Placement of Audio or Compact Disk-Read Only Memory Information on
Optical Disks

      With the advent of the new 120 mm optical media in block
type formats of Magneto-Optic (MO), Write Once Read Many (WORM),
Phase Change (PE), etc., a means of informing the user as to the type
of media being used is important to prevent misuse of the media or
user frustration.  This is done by adding an audio track that informs
the user of the type and use of the media.  This idea allows the user
to instantly and easily detect that the wrong media has been placed
in a CD or CD-ROM drive.

      With the advent of the new 120 mm optical media in block
type formats of MO, WORM, PE, etc., this new media size will fit
conventional CD, CD-ROM, CD-R, and CD-E drives but will not work due
to the vastly different and incompatible formats.  An audio track
with a brief message that states, for example, "This is not an audio
or CD-ROM disk, please remove from the drive..." can be placed in the
standard location for CD formats without affecting the MO or other
types of formats, which typically use a different location on the
media surface.  This will inform the user that this disk cannot be
used in his CD or CD-ROM drive and it could also inform the user as
to the type of media it is, how the information can be accessed, and
any number of audio messages that will fit within the allowable area.

      A label can also be used to inform the user that this is not
a CD or CD-ROM disk, but...
