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.

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.

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.

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.
