JVC UX-QD70S, UX-QD70W manual Restrictions on MDs, Serial Copy Management System Scms

Restrictions on MDs

MDs employ an original recording method different from those used for standard cassette tapes. Because the MD recording method has some restrictions, the following phenomena may occur. The phenomena are not a malfunction of this product.

You can make a clear digital recording from a CD to an MD. However, you are prohibited from duplicating the digitally recorded sound from that MD to another MD using the original digital signals. In short, you cannot make "a copy of a copy". This rule is called the Serial Copy Management System (SCMS). This product is designed to comply with this rule.

Serial Copy Management System (SCMS)

The Serial Copy Management System protects copyright and allows only first-generation digital copies from the digitally recordable source.

CD

CAUTION

•The SCMS does not permit you to record sound from a digitally recorded MD to other MD as digital sound.

•You cannot digitally record a digitally recorded CD-R/CD-RW to an MD. "SCMS CANNOT COPY" appears and the digital sound is converted to analog.

High Speed Copy Management System (HCMS)

You can record sound to an MD at a higher speed than normal recording. Therefore, restrictions are required in order to protect copyright.

When you use this product to record a track of a CD with the high speed recording function, this product does not permit you to use the high speed recording function to record the same track of a CD to an MD within 74 minutes of the start of the first recording.

For instance, when you record the first track of a CD to an MD with the high speed recording function, you cannot record the same track to an MD for 74 minutes after the first high speed recording started. In addition, when recording tracks from a CD with the high speed recording function, you cannot record 101 or more tracks within 74 minutes after recording starts. You can record up to 100 tracks in such a case.
