"Nonlinear" Recording Medium –
The Professional Disc
The Sony Professional Disc, PFD23A is a single-sided, optical disc that uses state-of-the-art blue-violet
laser technology to enable extremely large-capacity recordings.
The diameter of the disc is a mere 12 cm, equal to that of other optical media such as CDs or DVDs.
Yet, despite its small size, the disc provides an amazing storage capacity of 23.3 GB – a feat made
possible using a 405 nm blue-violet laser, an objective lens with a 0.85 numerical aperture (NA),
and a specially developed recording layer.
Sony has taken great care in selecting the Professional Disc as the next-generation professional
recording medium. The choice is based on Sony experience and technical expertise in developing
and marketing a wide range of professional products that have effectively served users around the
world for several decades.
