Σύνοψη

Audio CD Players are becoming a big part of everybody's life nowadays. Their price ranges from 100 to a few thousand pounds. An inexpensive and portable audio CD player can be developed using a PC's CD ROM A problem that arises when using a CD ROM for the listening of audio CDs only is that there is a large waste of energy from the rest of the PC .. This is because a 300W Personal Computer has to be used in order for a 10W CD ROM to operate. However with a few adjustments a CD ROM can operate without the need of the pc.
This project provides a solution for the above. When the CD ROM is connected to the PC, an audio CD Player program (software) is developed in order to extract the full range of audio capabilities of the CD ROM drive. The CD ROM is also controlled from the keyboard which is a new development. The monitop is not required when performing the basic audio functions, bringing down the power requirements to 200W.
The CD ROM can also function outside the PC as a stand alone unit, as it is already mentioned. In this case the hardware that will be provided is:
• A power supply
• An audio amplifier
• A track counter
Finally this work provides an answer to the question: Where do I connect my CD ROM?
In addition the different ways of interfacing a CD ROM to the PC, that can be found today can easily bring up some more questions.
• Is the most popular IDE interface the best?
• What if it isn't? ,
• What makes it the most popular interface?
