Disk apparatus for driving different kinds of optical disks and a method for identifying performance characteristics for a particular optical disk installed in the disk apparatus

An optical disk apparatus, comprising:

• an optical disk apparatus having a data read function from a CD-ROM disk, a data write function to a CD-R disk, a data write function to a CD-RW disk, a data read function from a DVD-ROM disk, a data write function to a DVD-R disk, a data write function to a DVD-RW disk, a data read function from a DVD-RAM disk and a data write function to a DVD-RAM disk;
• and
• a performance indication label attached on a surface of the optical disk drive unit, wherein:
• the performance indication label representing a first numeral for indicating a data transfer rate for the data read function from the CD-ROM disk, a second numeral for indicating a data transfer rate for the data write function to the CD-R disk, a third numeral for indicating a data transfer rate for the data write function to the CD-RW disk, a fourth numeral for indicating a data transfer rate for the data read function from the DVD-ROM disk, a fifth numeral for indicating a data transfer rate for the data write function to the DVD-R disk, a sixth numeral for indicating a data transfer rate for the data write function to the DVD-RW disk, a seventh numeral for indicating a data transfer rate for the data write function to the DVD-RAM disk and a symbol for indicating a data read function from the DVD-RAM disk that are arranged on a hypothetical circle.

A packaged unit comprising;

• an optical disk drive apparatus having data writing and data reading functions to and from different kinds of optical disks;
• a package for packing the optical disk drive apparatus;
• and
• a performance indication label affixed on a surface of the package, the performance indication label including a plurality of notation areas for identifying each performance characteristic for the respective optical disks.
