A Padus, Inc. Technology Overview Presented by PRO-G Japan Mirco Caramori Vice President, Operations, Padus Incorporated October 2002

A Padus History The Padus development team re-defined modern CD pre-mastering with the development of EasyCD ® application when working at Incat Systems ® Padus, Inc. founded in the heart of Silicon Valley (San Jose, California) – Padus was first to develop technology to operate several CD writing drives concurrently thus revolutionizing the professional CD duplication business.

A Padus History 1999 – Padus ships one of the most powerful CD programming toolkit allowing 3 rd party developers to quickly integrate optical data storage technology within their existing application. Today, the Padus Foundation Class Toolkit is used worldwide by most multimedia companies – Padus is first to ship a complete Internet / Intranet based CD/DVD pre-mastering and writing technology. This allows CD/DVD writing drives to be shared and accessed by multiple users simultaneously over local and global networks.

A Disc recording toolkit for Windows operating systems

A Overview The Padus Foundation Class for Windows operating systems is a software development toolkit for all types of CD/DVD reading and recording. The PFC allows developers to satisfy a product’s internal CD/DVD recording needs quickly and to get to market faster with an optical recording-enabled product. Programmers also can forgo the investment of supporting an ever-expanding list of hundreds of available drives -- so they can spend development time on the larger project at hand, where their expertise lies.

A Features Pure C/C++ object-oriented environment with no Win32 UI coding Support for Windows ® 95/98/Me/NT/2000/XP Independent ASPI layer Includes many sample applications (with source code) that illustrate the most common CD/DVD tasks Full 32-bit multi-thread and multitasking implementation Small footprint (the whole toolkit is contained in one single DLL of ~1MB)

A Features Support for all CD-R, CD-RW, DVD-RAM, DVD±R, and DVD±RW drives currently available (SCSI and ATAPI) Support for simultaneous recording to multiple CD-R, CD-RW, DVD-RAM, DVD±R, and DVD±RW drives Full support for IEEE-1394 (Firewire) and USB 1.1/2.0 protocols Support for CD/DVD autoloaders and jukeboxes

A Developer Assistance Our expert engineering staff is available to work with our customers and -- upon request -- develop new features, components or custom interfaces to considerably ease the integration of our toolkit. Customizations have been provided in the past to support proprietary hardware, system architectures, and applications. Our turnaround time for compatibility issues is well known and respected within development teams.

A Network CD/DVD mastering for Windows operating systems Built on Padus Foundation Class technology

A Overview DiscJuggler.NET is an architecture based upon the idea of sharing CD and DVD writing drives over the network. In the same way that printers have been used in a networking environment, DiscJuggler.NET can be used to give clients unlimited or even limited access to CD/DVD writing drives. All of the timely functions of writing a disc, like pre- mastering and extraction, can happen on the client systems instead of the host system.
