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.

Key Capabilities

• 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

Advantages and Benefits

• 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

Media compatibility

• 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
