Technical Notes

Buffer Underrun Protection Function

CD-R/RW drives are equipped with a buffer memory, which temporarily stores data
that is being transferred. When the buffer memory becomes empty due to a delay of
data transfer for any reason, a writing error happens. Such condition is defined as
buffer underrun, and such an error is defined as a buffer underrun error.

Buffer Underrun Protection is featured in the CRW-F1UX drive.

When buffer underrun almost happens, Buffer Underrun Protection temporarily
suspends the writing process. Writing resumes when enough data has accumulated
in the buffer memory. Buffer Underrun Protection in the CRW-F1UX drive is
extremely accurate, resulting in seamless recording before and after suspension.

Test writing

Test writing is a function to check for the possible occurrence of buffer underrun in your
computer environment. When Buffer Underrun Protection of the CD writing software is
activated, the test writing function cannot be operated. Buffer Underrun Protection
should be deactivated to operate the test writing function.

35

Technical Notes

Writing Methods

Disc-at-Once (DAO)

This method is used to write all data onto a disc in one operation. It writes multiple
pieces of data without placing a space between data, starting with the innermost
track of the disc. Once data is written by this method, no data can be added to the
same disc even if there is free space available on the disc. This method is useful for
making a backup copy of an entire disc.

Track-at-Once (TAO)

This method is used to write data on a disc on a track-by-track basis. A track can be
defined as the smallest unit of area that contains an ordinary program, image file,
text file, etc. This method enables you to add data to the same disc, one track of data
at a time, as long as there is free space available on the disc. A disc that contains data
written in several sessions is defined as a multi-session disc.
An area that records data and management information (Lead-in/Lead-out) is
defined as a session. Lead-in and Lead-out are signals written for stating the starting
and ending points of one session.

Note

Ordinary audio CD players can only play back single-session discs or the first session on
a multi-session disc. Do not record audio data on the second and subsequent sessions.

Session-at-Once (SAO)

This method is used to write data on a disc on a session-by-session basis. Unlike
Track-at-Once described above, Session-at-Once enables you to record multiple
tracks onto a disc at a time. CD EXTRA, for example, uses this method to write
multiple pieces of audio data (or multiple tracks) in the first session and information
required for computers in the second session. This method enables you to add data
into the same disc, one session at a time, as long as there is free space available on
the disc. A disc that contains data written in several sessions by this method is
defined as a multi-session disc, like a disc written by the Track-at-Once method.

36

Packet Writing

This method is used to record data onto a disc on a file-by-file basis. This method
divides a track into small segments called “packets” so that data can be written on a
packet-by-packet basis, which means that you can write data in much the same way
as you copy data to a floppy or hard drive. Since the data can be written easily,
packet writing is proper to daily data backup. Packet writing also enables you to add
packets to a disc as long as there is free space available on the disc.

Note

• Discs need to be formatted for packet writing prior to use.

• Formatting a CD-RW disc using packet writing software reduces its storage capacity
by about 100MB since packet writing requires exclusive space for itself.

• For CD-R discs, deleting data means masking data but not actually removing data.
Therefore, actual free space in a CD-R never be increased even if data is deleted.

Audio Master Quality Recording (High quality audio writing mode)

This method enables you to record high quality data that can be played back with the

1.4 m/s linear velocity.

Note

• Audio Master Quality Recording is enabled with the 1X-, 4X-, or 8X-speed Disc-at­Once writing method.

• Maximum recording time is 63 minutes for a 650MB CD -R disc and 68 m inutes for a
700MB CD-R disc.

• Audio CDs that are created with Audio Master Quality Recording may not be played
back on certain audio recorders and CD-R/RW drives.

CD-MRW (CD Mount Rainier ReWriting)

This method is a new standard of packet writing for a CD-RW disc and supports
defect control by the drive, background formatting, and disc ejecting during
formatting. It enables you to use a CD-RW disc like a floppy disk.

Note

Formatting a CD-RW disc using CD-MR W reduces its storage capacity by about 150MB
since CD-MRW itself requires exclusive disc space.

37

Technical Notes

Constant Linear Velocity (CLV)

The disc rotation speed is adjusted to keep the data transfer rate constant while
writing/reading data.

Constant Angular Velocity (CAV)

The data transfer rate is adjusted to keep the disc rotation speed constant while
writing/reading data. The Full CAV method employs CAV all through data writing/
reading.

Partial CAV

The CAV method is employed for inner tracks of a disc and the CLV method for
outer tracks while writing/reading data.
