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.
