Finalization
This is the final process in recording on a CD-R or CD-RW.
“Finalizing a disc” means to finish writing the TOC (Table of
Contents) on the recorded disc. Only after this process is completed,
a recorded CD-R or CD-RW can be played back on a CD player
compatible with CD-R/CD-RW.
Sampling Frequency
When analog signals are converted into digital signals, they are
divided into many points and digitized. This dividing method is
called “sampling.” The sampling frequency indicates how many
points one second is divided into – for example, for CD sound, one
second is divided into 44100 points since its sampling frequency is
44.1 kHz.
SCMS (Serial Copy Management System)
Digital audio components, such as CD recorder, MD (Mini-Disc)
recorder and DAT (Digital Audio Tape) recorder, can exchange
audio signals in the digital forms through digital input/output
terminals. The digital audio components allow digital copy of music
signals with little deterioration. This has made it necessary to have a
copy restriction rule for protecting the copyright, and “SCMS
(Serial Copy Management System)” has been established as a
result.
To protect the copyright, the SCMS allows only first-generation
digital copies to be made from premastered software (like CDs or
prerecorded MDs).
If you try to record from such copied discs on this unit, the
PROHIBIT indicator will light up on the display.
OPC (Optimum Power Control)
OPC is a function that checks the loaded disc and automatically
adjusts the laser for optimum recording setting before recording
through the Digital Optical Input terminal.
TOC (Table of Contents)
TOC is a kind of disc information containing sub-data (track
number, playing time, etc.) that enables us to search for tracks
quickly on the disc.
To write the TOC on a CD-R or CD-RW, you need to finalize the
disc.
Track mark
When playing a disc, you can move among the tracks.
You can do this because there is a mark recorded at the beginning of
each track enabling you to locate the track. This mark is called a
“track mark” and the portion between two adjacent track marks is
called a “track.”
Unfinalization
This means to erase the TOC (Table of Contents) on a finalized CD-
RW. This makes it possible to erase the recorded data from the CD-
RW.
