• Virtual drive is a device that appears as an ordinary physical disc drive to the operating system . Such devices are added to the operating system with special software called a disc emulator.
  • CD/DVD emulation — is an imitation of the drive creation via the special software. CD/DVD disc image files are used as real CD/DVD discs for such virtual CD/DVD drives.
  • Disc image — is a single file containing the complete contents and structure representing an optical disc.
  • SPTD driver — SCSI Pass Through Direct (usually abbreviated as SPTD, filename "sptd.sys") — is a device driver developed by Duplex Secure Ltd. that provides a method of access to storage devices. It can be used for work with virtual drives in DAEMON Tools for advanced emulation.
  • Virtual SCSI adapter: SCSI (Small Computer System Interface) is a standard of connecting of peripheral units by the special board — SCSI-adapter. Virtual realization of hardware SCSI adapter intended for connecting of virtual CD/DVD devices is a virtual SCSI adapter.
  • Virtual IDE adapter: IDE adapter is the parallel interface of connecting of stores (hard disks and optical drives) to the computer. Virtual realization of hardware IDE adapter intended for connecting of virtual CD/DVD devices is called a virtual IDE adapter.
  • Image mounting is an analogy of real CD/DVD disc loading to physical CD/DVD drive.
  • Image editor is a part of DAEMON Tools Pro software functionality intended for CD/DVD disc images editing and new images compilation.
  • Image grabbing is copying all content and structure of file system and data from CD/DVD disc to the file (sometimes into several files) called image file to save it to the hard drive or another media.
  • Emulation is the reproducing of the device behavior using other software or hardware methods, or software and hardware combination methods. The main goal is an exact modeling of imitated system status and behavior.
  • Images catalog is a part of DAEMON Tools Pro software functionality for organizing of disc images and virtual hard disks collection.
  • mdx / mds (Media Data eXtended / Media Descriptor Files) — the formats developed by DAEMON Tools developers. Other formats are used in another CD/DVD emulating software. DAEMON Tools supports the following formats.
  • RMPS: DPM can be observed and subsequently encoded into a Recordable Media Physical Signature(RMPS). In concern with emulation software, RMPS can reproduce the effects of DPM for backup copies of CD/DVD media. This technique was invented by DAEMON Tools, for which it created the mdx / mds file formats.
  • Virtual Bus driver is a driver for basic device emulation. Provides optical disc drive emulation and it aims to help you avoid many compatibility issues with other software.
