ENGLISH
Cleaning discs
šIf there are fingerprints or dirt on a disc, wipe them off before 
using the disc. Fingerprints and dirt can impair sound quality 
and cause interruptions in playback.
šUse a commercially available disc cleaning set or a soft cloth 
to clean discs.
Gently wipe the disc from 
the inside towards the 
outside.
Do not wipe in a circular 
motion.
NOTE
Do not use record spray, antistatic agents, benzene, thinner or 
other solvents.
Explanation of terms
B
Bit rate
This is the amount of audio data recorded on a disc that is read 
in one second. 
D
Dynamic range
The difference between the maximum, undistorted sound 
level and the minimum sound level that is discernible above 
the noise emitted by the device.
F
Finalizing
This process enables CDs recorded with a CD recorder or 
drive to be played by other players.
L
Linear PCM
This is an uncompressed PCM (Pulse Code Modulation) signal. 
This is the same system used for CD audio but uses 192 kHz, 
96 kHz, and 48 kHz sampling frequencies on Blu-ray Disc or 
DVD and provides higher resolution than CD.
M
MP3 (MPEG Audio Layer 3)
This is an internationally standardized audio data compression 
scheme, based on the “MPEG-1” video compression standard. 
It compresses the data volume to about one eleventh its 
original size while maintaining sound quality roughly equivalent 
to a music CD.
S
Sampling frequency
Sampling involves taking a reading of a sound wave (analog 
signal) at regular intervals and expressing the height of the 
wave at each reading in digitized format (producing a digital 
signal).
The number of readings taken in one second is called the 
“sampling frequency”. The larger the value, the closer the 
reproduced sound is to the original.
W
WMA (Windows Media Audio)
This is the audio compression technology developed by 
Microsoft Corporation.
To encode WMA files, only use applications authorized by 
Microsoft Corporation. If you use an unauthorized application, 
the file may not work properly.
