Image Mastering API
Windows applications such as Windows Media Player, Windows Media Center, Windows Movie Maker, Windows DVD Maker, and Windows Explorer use IMAPI to create ISO images and "burn" discs. Windows refers to discs created using IMAPI as Mastered burns in contrast to the term, Live File System which implies packet writing and does not use IMAPI.
Release history 
IMAPI was originally introduced with Windows XP. IMAPI version 2.0 was released with Windows Vista and Windows Server 2008. O of the Image Mastering API v2.0 (IMAPIv2.0) update package that is dated June 26, 2007 (MSKB932716)
| publisher = Microsoft | work = Microsoft Support | date = 11 October 2007 | accessdate = 12 December 2007
On 19 January 2009, Microsoft released the Windows Feature Pack For Storage 1.0. This update allows IMAPI 2.0 to support Recordable Blu-ray Disc (BD-R) and Rewritable Blu-ray Disc (BD-RE) media. It also adds support for the Universal Disk Format (UDF) 2.5 file system. Windows Feature Pack for Storage is available for Windows XP or later and is integrated into Windows 7.
IMAPI provides the ability to create and burn single-session and multi-session discs, including bootable discs. It also provides low-level access to the burn engine for developing support for new devices, as well as access to extended recorder properties. IMAPI supports every major writable CD and DVD format including:
- DVDs (IMAPI v2.0)
- Recordable DVD (DVD-R and DVD+R)
- Rewritable DVD (DVD-RW and DVD+RW)
- Recordable dual layer DVD (DVD-R DL and DVD+R DL formats)
- Random-access DVD (DVD-RAM)
- Blu-ray discs (IMAPI v2.0 with Feature Pack for Storage)
IMAPI version 2.0 supports the following additional features:
- User-mode API instead of a kernel-mode API
- Support for multiple optical drives as well as simultaneously recording to multiple drives
- Support for creating ISO images
- Support for VBScript scripting
- Support for locking the recorder while burning 
IMAPI 2.0 suffers from some limitations, notably that will not allow a filesystem to be imported from a raw image (.iso file), only from an optical drive. In effect this means that while it can generate disk images, it cannot be used to modify them.
