What is Orange Book? The Orange Book is a collection of standards for CD-R and CD-RW, and sometimes refers to the standards themselves. The Orange Book Part 2 deals chiefly with CD-R discs, and the Orange Book Part 3 with CD-RW discs. The book takes its name from its orange colored cover. Audio CDs and CD-ROMs Ordinary audio CDs that can be played back on a CD player contain sounds or music data data recorded in a format called CD-DA (Compact Disc-Digital Audio). This means that CD-R discs

Handling Discs and Data Partial CAV (Constant Angular Velocity) The CLV (Constant Linear Velocity) method is generally used to write data on a CD-R disc. In writing by the CLV method, the disc rotation speed is adjusted to keep the data writing speed (data transfer rate) constant at any part of the disc. In contrast, the CAV method (Constant Angular Velocity) method exercises control so as to keep the disc rotation speed constant. The CAV method makes it possible to substantially increase t

Buffer Underrun defined CD-R/RW drives are equipped with a buffer memory. This memory temporarily stores data while a disc is being recorded. When the buffer memory becomes empty (due to unexpected interruptions or the system’s inability to keep up with the writing process), a writing error occurs. This error is known as a “buffer underrun error.” Data If data transfer is interrupted... Data is stored in then the buffer When no data is the buffer memory begins left in the buffer memory...

Hard drive space Writing data on a CD-R/RW disc requires 50 MB to 100 MB of free space as a working area on the hard drive. When writing data on a CD-R/RW disc after creating an image file, there must be enough free space on the hard drive to store the image file in addition to the working area (a total of up to about 900 MB). However, this hard drive space for image files is not needed when directly writing onto a CD-R/RW disc from a hard drive or CD-ROM using the CRW-70 drive (on-the-fly
