Professional Disc (PFD) is a

CD and red laser technology used in the DVD

format.

Technology

PFD uses a 405

Mbit/s

for reading and 72 Mbit/s for writing. After the 23GB disc was released, a dual-layer 50 GB was developed and released.

This format is sometimes confused with the

Blu-ray Disc format, another optical disc format using blue-violet lasers and supported by Sony. Even the PFD's caddy and Blu-ray's original caddy (later dropped) looked very similar. Capabilities differ; single-layer PFD discs have a capacity of 23 GB whereas Blu-ray discs can store 25 GB. However, Blu-ray discs currently allow a 2x data transfer rate of 72 Mbit/s – lower than PFD. This is because PFD discs use much higher quality media and drives use higher quality components, making them prohibitively expensive for the consumer segment to which Blu-ray is aimed. PFD discs can have a capacity of up to 100 GB for rewritable discs, and 128 GB for write-once discs.^[1]
