Sony XDCAM Disk- 23GB, PFD23A
New "Nonlinear" Recording Medium- The XDCAM Professional Disc. The Sony XDCAM Professional Disc media, PFD23A, is a newly developed, 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 XDCAM Professional Disc media 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.
Flexible Platform
The XDCAM Professional Disc system is a very flexible platform on which an assortment of data in a variety of formats can reside. The use of optical disc technology eliminates the restrictions inherent in proprietary tape footprints, and allows a variety of different video formats to be recorded as 'data files', and is therefore extremely flexible as to what can be recorded to it. In addition to video and audio streams, you can record a variety of metadata, such as date/time information and comments indicating the material content. Furthermore, computer files created on Microsoft Word, PhotoShop, and other application software can also be stored on the XDCAM Professional Disc media*. *Up to 500 MB
Largest-Capacity Optical Disc
The superior disc capacity of the XDCAM Professional Disc media enables you to make high-quality, yet long duration recordings. Its 23.3GB data capacity translates to a recording time of 45 to 85 minutes depending on the bit rate the camera the operator chooses.
High Transfer Rate
The XDCAM Professional Disc's data transfer rate is 72 Mb/s from a single optical head unit and 144 Mb/s on a dual head deck, providing stable recording and playback of high bit rate data such as a 50 Mb/s MPEG IMX stream.
Quick Random Access
The nonlinear nature of the XDCAM Professional Disc media alone provides tremendous benefit when handling audio/video content. When a recording is played back from the disc, its physical location on the disc does not impact the time required to access it. Recordings can be accessed in a fraction of the equivalent time taken to access information on disc, making it much easier and faster to locate source material. This is the beauty of random access, and all Sony XDCAM products are equipped with powerful features- delivering innovation to all your programming operations.
Highly Reliable, Durable and Re-usable Medium
XDCAM optical discs have a natural advantage since they suffer no mechanical contact during recording or playback, making the format ideal for continuous use and re-use. The XDCAM Professional Disc media is highly resistant to dust, shock, and scratches, and is packaged in an extremely durable and dust-resistant cartridge. It is resistant to heat and humidity, and is X-ray resistant - factors that make the XDCAM Professional Disc media ideal for use in harsh field environments, and also allows for long media life and long-term storage.
Also known as 23A, formerly PFD23A now PFD23A/2.
