can hold 7 times the amount of data contained in a CD-
ROM, which translates to 4 consecutive hours of playing
time (8 hours for double-sided discs). DVD discs are
divided into 4 types: single sided single layer, single sided
double layer, double sided single layer, and double sided
double layer.

Super Audio CD (SACD)
An SACD disc can reproduce sounds that are extremely
faithful to the original sound by use of DSD (Direct
Stream Digital) technology. This technology utilizes a
sampling frequency of 2.8224MHz, which is 64 times that
of a conventional CD, and 1-bit quantization that enables
the disc to hold 4 times the amount of information that a
standard PCM format CD can hold. SACDs are divided
into the following types.
• Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
Press SACD/CD repeatedly so that the SACD indicator
on the player lights up.
* High density signal layer for the Super Audio CD
