Patent number: 8687476Abstract: A method and an optical storage medium are provided for storing data to and accessing data from an embedded virtual medium within the optical storage medium. Information describing the embedded virtual medium may be stored on to the optical storage medium. Space for an embedded lead-in area of the embedded virtual medium, as well as user data for the embedded virtual medium, may be allocated within a data zone of the optical medium. A spare sector bitmap may be included in a lead-an area of the optical medium indicating spare sectors within the embedded virtual medium as being unavailable. A spare sector bitmap may be included within the embedded virtual medium indicating available spare sectors of the embedded virtual medium. Physical sector/logical block mapping of the optical storage medium may be modified for accessing data stored on the embedded virtual medium.Type: GrantFiled: May 31, 2011Date of Patent: April 1, 2014Assignee: Microsoft CorporationInventors: Henry Paul Gabryjelski, David Burg, Ravinder Singh Thind

Patent number: 8103823Abstract: A method and a host processing device are provided for background formatting, or de-icing, an optical medium with no de-icing assistance from an optical drive upon which the optical medium is mounted. In a foreground mode, an optical medium may be initially formatted, volume structures may be recorded on the optical medium, file system information may be written thereto, and quick grow formatting may be performed to make the optical medium writable, at least sequentially. Under initiation and control of a file system, executing on a host processing device, the optical medium may be formatted, or de-iced, in a background mode with no assistance from an optical drive, upon which the optical medium is mounted. Under control of the file system, blocked input or output activity, may be allowed to access the optical medium upon pausing the formatting, or de-icing.Type: GrantFiled: August 14, 2008Date of Patent: January 24, 2012Assignee: Microsoft CorporationInventors: Ravinder Singh Thind, Martijn de Kort, Darren Glen Moss
