| 20080232210 | Data Recording/Reproduction for Write-Once Discs - A file system is enabled to use a Metadata Partition instead of VAT for write-once discs, and is provided by a pseudo-overwrite method with a plurality of tracks especially for metadata and file data. On applying this invention to a drive apparatus that supports pseudo-overwrite media, the file system distinguishes data to overwrite from data to append (S | 09-25-2008 |
| 20080310289 | Data Recording/Reproduction for Write-Once Discs - A recording method of the present invention includes the steps of: receiving a write instruction which specifies at least a logical sector in which data is to be written; determining whether the logical sector specified by the write instruction corresponds to a recorded physical sector or an unrecorded physical sector (S | 12-18-2008 |
| 20110055182 | FILE SYSTEM - In response to a request to a file system to perform a requested update, a lock of a first node in a file system can be acquired, and an update of the first node can be performed while the lock of the first node is held. Also in response to the request, a lock of a second node can be acquired, and an update of the second node, which reflects the update of the first node, can be performed while the lock of the second node is held. The update of the first node can be independent of acquiring the lock of the second node. A file system can allow a pair of update operations to be performed in parallel where both operations include updating the same container node. Additionally, while a file system is running, new namespace types can be defined, and the file system can be extended to manage nodes within the new namespace types. | 03-03-2011 |
| 20110055184 | FILE SYSTEM - For each of one or more existing nodes in a file system, pending notifications of updates that have been performed on the node can be identified and sent to one or more other nodes. The file system can be opened for use, and one or more other nodes can be updated in response to the pending notifications while the file system is open for use. For example, this may be done in an operation for recovering from a crash of the file system. Also, a process for dealing with stale data in container nodes in a file system can include processing access requests according to a stale data scheme. | 03-03-2011 |
| 20110099348 | CONTROLLING MEMORY VISIBILITY - Embodiments are disclosed herein that are related to controlling the visibility of a portion of memory in a hardware device. For example, one disclosed embodiment provides a hardware device comprising a communications interface configured to connect to a complementary communications interface on a computing device. The hardware device further comprises a portion of memory having a first ID configured to cause the portion of memory to be visible to a user of the computing device to which the hardware device is connected. Further still, the hardware device comprises instructions stored in the portion of memory which are executable by and transferable to the computing device to cause the installation of a computer program related to the hardware device, and to cause the portion of memory to be hidden from the user of the computing device upon transferring of the instructions to the computing device. | 04-28-2011 |
