AuthorScript® Storage SDK

Available for Windows, Macintosh, and Linux, the AuthorScript Storage SDKs allow application developers and service providers to quickly integrate powerful capabilities for recording, copying, and archiving to recordable/rewritable BD, DVD, and CD media. Covering file structure creation and management, file reading and writing, device control, and output to either optical media or disc image, AuthorScript Storage is a full-featured solution ideal for both one-off and industrial-scale applications.

AuthorScript Storage is provided as a set of C++ libraries that enable the functionality needed at each level for effective volume/file creation, management, and output:

Volumes:

  • open existing on-disc volumes
  • create new volumes
  • read file structure information (mount volume)
  • set volume format (ISO, UDF 1.02, UDF 2.0, etc.)
  • flush updated volume file structures to disc

Entries and files:

  • create file structure entries (directories and files), including references to files from streams or stored on hard drive
  • read from and write to files
  • get entry information and get/set entry properties
  • delete entries

Devices:

  • manage devices, including counting, selection, and settings
  • get device state and get/set properties of devices and media
  • copy from one drive to one or more others
  • copy from drives to disc images, and vice versa
  • burn volumes to devices containing recordable/rewritable BD, DVD, or CD media
  • execute commands such as media erasure and tray control

Advanced features:

  • prepare output of higher-level logical formats (e.g. BDAV, BDMV, DVD-Video, CD-Audio) to hard drive as image formats, including DDP, CMF, ISO, and GI
  • create specification-compliant disc layouts with each element in its correct logical sector
  • utilize three available volume access modes, each tailored to different use scenarios: ReadOnly, Mastering, or RTTD
  • utilize all major write modes, including Session-at-Once (SAO or DAO), Track-at-Once (TAO), and Test Mode

AuthorScript Storage SDKs offer the following key advantages over competing disc-burning solutions:

Reliability:

  • 24/7 uptime assurance (no machine lock ups)
  • device access protection shields operations in progress from outside interference

Performance:

  • multiple threads on a single process allow concurrent burns to different devices
  • file system is cached, then flushed in one sequential write, avoiding incremental updates
  • native 32-bit and 64-bit binaries

Real-Time To Disc (RTTD):

  • record direct to disc in real time (streaming)
  • write to a file without knowing total data size in advance

    Entry-based mastering:

  • write either complete directories or individual files
  • use callbacks to control timing and flow of data transfer

File system control:

  • create and manipulate file system objects
  • easily migrate products based on standard file system calls

Device support:

  • SilentSelect™ automatically supports new optical devices without ongoing application maintenance

Multiple language support:

  • native C++ interface
  • managed .NET interface for C#, J#, and Visual Basic
  • Java interface

Built-in diagnostics:

  • bus tracing and logging
  • API tracing and logging

AuthorScript Storage offers comprehensive output media/format support, enabling retrieval/playback of recorded data across a wide variety of environments:

  • Output media - support for BD-R, BD-RE, DVD-R/+R, DVD-R DL/+R DL, DVD-RW/+RW, DVD-RAM, CD-R/RW, HD DVD-R and HD DVD-RW
  • File systems - read/write support for ISO, Joliet, and UDF volume formats
  • Portability - recorded discs deliver the same playback portability as factory-replicated discs, including platform-independent computer-hosted playback
