JVC XL-R2010BK manual SCMS Serial Copy Management System, Glossary

Due to copyright and other considerations, the following restriction is now in place for CD-R and CD-RW discs onto which the digital signals of CDs have been copied.

SCMS (Serial Copy

Management System)

The digital quality of CDs and other digital media can be recorded to CD-R and CD-RW using the CDR function of this unit. How- ever, it is not possible to make a second generation digital copy from a first generation copy. This restriction, known as SCMS (Serial Copy Management System), is intended to prevent unlim- ited digital copying in the interests of artists and other copyright holders.

This unit is designed to comply with SCMS restrictions.

Glossary

The following is a brief description of some of the acronyms used in this manual.

ATIP (Absolute Time in Pregroove)

The reflected light returned from the pregroove of a CD-R disc generates a carrier signal providing tracking, motor control and focus signals. Additional information including the Recommended Optimum Recording Power value is also encoded in a frequency modulation of the carrier signal.

CD-R (Compact Disc-Recordable)

The reference to recordable disc media. Also often referred to as write-once discs as data can only be recorded one time.

OK NO CD-RW (Compact Disc-ReWritable)

Source CD	Digtal	First generation	Second generation
	Recording
		copy (CD-R or	copy (CD-R or CD-
		CD-RW)	RW)

The copyright laws allow recordings to be made for the personal enjoyment of the individual user but they do not allow such record- ings to be used for any other purpose without permission from the rightful owner of the copyrights.

Note

•If digital recording of a first generation digital copy is attempted, “SCMS PROTECT” is shown in the information dis- play, and the recording operation is canceled.

•In the case of synchronized recording operations, Listening Edit recording and Program Edit recording, when the first-genera- tion copy is a finalized CD-R or CD-RW disc loaded in the CD player, the recording type is automatically changed from digital to analog, and the recording type indicators light accordingly. (If high-speed dubbing is turned on, it will be turned off when the recording type is changed.)

Recordable disc media to which data can be recorded and erased repeatedly.

OPC (Optimized Power Control)

Analysis of recordable CD media to determine the optimum power setting for recording of data to the disc.

PCA (Power Calibration Area)

A space reserved at the beginning of a disc for calibrating the laser power needed to record that disc.

PMA (Program Memory Area)

On a recordable disc, it is the area that “temporarily” holds the information about the recordings on the disc: the track numbers and the track starting and stopping points when written in a session that is not yet closed (unfinalized disc). When the session is closed (the disc is finalized), this information is written to the TOC.

TOC (Table of Contents)

The area on a CD to which is recorded various information of the disc contents such as the number of tracks, their starting points, and the total length of the data area.
