Sony RMT-D165A Manual

MP3 is audio compression technology that 
satisfies the ISO/MPEG regulations. JPEG is 
image compression technology.

You can play back DATA CDs (CD-ROMs/
CD-Rs/CD-RWs) recorded in MP3 (MPEG1 
Audio Layer 3) and JPEG format. However, 
the discs must be recorded according to 
ISO9660 level 1, level 2 or Joliet format for 
the player to recognize the tracks (or files). 
You can also play discs recorded in Multi 
Session.
See the instructions supplied with the CD-R/
CD-RW drives and the recording software 
(not supplied) for details on the recording 
format.

If MP3 audio tracks or JPEG image files are 
recorded in the first session, the player will 
also play MP3 audio tracks or JPEG image 
files in other sessions. If audio tracks and 
images in Music CD format or Video CD 
format are recorded in the first session, only 
the first session will be played back.

The player may not be able to play some DATA 
CDs created in the Packet Write format. In this case, 
you cannot view the JPEG images recorded.

The player can play the MP3 audio tracks or 
JPEG image files:
• which have the extension “.MP3” (MP3 

audio track), “.JPG” or “.JPEG” (JPEG 
image file)

• which conform to the DCF* image file 

format

* “Design rule for Camera File system”: 

Image standards for digital cameras 
regulated by Japan Electronics and 
Information Technology Industries 
Association (JEITA)

• The player will play any data with the extension 

“.MP3”, “.JPG” or “.JPEG” even if they are not in 
MP3 or JPEG format. Playing this data may 
generate a loud noise which could damage your 
speaker system.

• The player does not conform to audio in MP3PRO 

format.

The playback order of albums, MP3 audio 
tracks, or JPEG image files recorded on a 
DATA CD is as follows:
◆Structure of disc contents

Tree 1

Tree 2

Tree 3
