For playing audio CD, please insert Head-phone jack. The world of CD-ROM technology is not as confusing as your instruction manual. The same format is used for audio Compact Discs. Because of its high storage capacity, reliability, and low cost, CD-ROM has become an increasingly popular storage media. They also typically support playing audio CDs via an external headphone jack or line level output.
Some CDs also allow reading the frames of data from audio CDs in digital form.
With appropriate software, you can view the images on a computer, manipulate them, or send them to a printer. They use a different media and specialized equipment for recording, but the resulting disc can be read by any CD-ROM drive. In the future CD-ROM drive vendors are expected to offer new technologies that will increase storage capacity by an order of magnitude.
