2. PRODUCT DESCRIPTIONS

The PDR-555RW series (PDR-555RW, PDR-V500 and PDR-
19RW) is the first series of CD recorders from PIONEER that
supports recording and erasing of CD-RW discs. Basic operations
with CDs and CD-Rs with this series are based on those of the CD
recorders of the PDR-05 series.
The main differences from the PDR-05 series concerning the circuits
are:
• The pickup is changed.
• The circuit in RF amplifier is changed.
• The LD drive circuit (including the strategy control circuit) is
changed.
• A running OPC circuit is added.
• The focus servo, tracking servo and sled servo are digitized.
• The driver IC is changed.
• The CD decoder IC is changed.
• The sampling rate converter IC is changed.
• The DA converter is changed.
Also, the circuits of the CD recorders of the PDR-509 series are
based on those of the PDR-555RW series. So the main circuits
used in the PDR-509 series are equivalent to those of the PDR-
555RW series. But as an exception, AD converter is changed to the
AK5340-VS from the PCM1800-1.
