MP3-Formatted File

Outline of CD-R and CD-RW

• Definition

― CD-R: The CD-R is a non-rewritable version. Once a section of a CD-R is written, it cannot be erased or rewritten.

― CD-RW: The CD-RW is a re-writable version of CD-ROM and the data can be written an unlimited number of times.

― Since the reflected laser beam amount of a CD-R/RW is less than the reflected laser beam amount of the conventional CD media, the CD player/changer may not play the CD-R/RW or the sound may jump.

― Since the recording quality of the CD-R/RWs vary widely, some CD-R/RWs may not play.

Recording method

• There are two methods for recording.

• Classification by recorder

― Record the audio data in the audio-CD by audio recorder

• The price of the audio recorder and original audio-CD include the copyright fee.

― Record the audio data to a conventional data-CD using a personal computer

• The data-CD is cheaper than the audio-CD. But, there are lower quality CDs.

• Classification by audio data extraction/compression

― Extracted audio data

• The CD-R/RW player can play the extracted audio data.

― Compressed audio data

• It is possible to record a large quantity of music to a disc. The sound quality varies depending on the audio data compression format. The compressed audio data can be played on the applicable player only.

― Types of compression format:

• MP3: MPEG Audio Layer 3—Mazda genuine MP3 applicable CD player is available.

• WMA: Windows Media Audio

• ATRAC: Adaptive TRansform Acoustic Coding

MP3
