Abstract

Methods and apparatus for the recording of data to an optical media are provided. In one example, a method includes the selection of data to be recorded by a client application. After interface with an image mastering application programming interface, the selection of an optical media format, and the selection of an optical media recording device, the selected data is sent to a stash file. A task list of operations to be performed in the recording of the selected data is created, and the data is recorded by executing the task list from Kernel Mode of an operating system. In another example, an image mastering application programming interface is provided. The image mastering application programming interface is a collection of COM objects including a disk master, a stash file, a disk recorder, and a burn engine. In another example, a computer readable media having program instructions for the recording of data to an optical media is provided. The program instructions enable the selection of data, sending the data to a stash file, creating a task list for the recording of the data, and executing the task list from Kernel Mode of an operating system.
