20080205635 | APPARATUS, SYSTEM, AND METHOD FOR SELF-DESCRIBING HETEROGENEOUS MAGNETIC TAPE FORMATTING - An apparatus, system, and method are disclosed for self-describing, heterogeneous magnetic tape formatting. A detection module determines if data is to be encrypted when written to a magnetic tape in response to a host command and if the data is already encrypted. An encryption module encrypts the data if the data is to be encrypted and if the data is not already encrypted. A write module writes a reserved codeword followed by the data to the magnetic tape wherein the reserved codeword is configured as an encryption reserved codeword if the data is encrypted. If the data is not encrypted, the reserved codeword is configured as a clear reserved codeword. The encrypted and unencrypted data segments are intermixed on the magnetic tape. | 08-28-2008 |
20110157741 | LINEAR RECORDING DEVICE FOR EXECUTING OPTIMUM WRITING UPON RECEIPT OF SERIES OF COMMANDS INCLUDING MIXED READ AND WRITE COMMANDS AND A METHOD FOR EXECUTING THE SAME - A tape recording device, method, and computer program product are provided for performing operations of position movement, reading, and writing on a tape medium, and receiving a series of commands from an upper-layer device. The tape recording device includes a buffer for temporarily storing data related to the reading and an additional writing, a tape for recording the data stored in the buffer, a reading and writing head for reading data from the tape into the buffer and writing the data onto the tape, control means for reading data from a designated position of the tape and storing the data in the buffer, and for writing the data stored in the buffer onto the tape from a written data end position in response to an additional writing command, and a non-volatile memory for storing data stored in the buffer in response to an additional writing command. | 06-30-2011 |
20110176238 | APPARATUS FOR CONTROLLING WRITING DATA AND METHOD FOR THE SAME - In a controller of a tape drive, when a command processor receives a command for moving to the end of data (“EOD”) or the like, an operation signal output unit suspends the moving of a tape and a cartridge memory (“CM”) input/output unit stores therein a state of the tape in which the moving has been omitted. Then, when the command processor receives a command for writing data in this state, the CM input/output unit writes the data to a cartridge memory. Subsequently, for example, when a head passes a proper position at which the data should be actually written to the tape, the CM input/output unit reads the data from the cartridge memory, and the channel input/output unit writes the data to the tape at the proper position. | 07-21-2011 |

20140181344 | Detection of Abnormal Operation Caused by Interrupt Processing - A controller for controlling interrupt processing in a multiple-interrupt system is provided. The controller includes multiple watchdog timers (WDTs), each provided for each of interrupt priorities. The controller includes interrupt priority selectors, each of which receives each interrupt request signal and outputs an activation signal to a corresponding WDT according to the priority of the interrupt request signal. The controller includes an interrupt processing circuit, which when a WDT has timed out, outputs, to a processor, an interrupt request signal having a priority one or more levels higher than the priority corresponding to the WDT. When multiple causes of interrupt are assigned to one of the interrupt priorities, the interrupt processing circuit gives priority to an interrupt request signal caused by the timeout of a WDT lower in priority level than the interrupt priority to detect that an abnormal operation has occurred in interrupt processing having the lower level priority. | 06-26-2014 |
20140195745 | Data Storage Mechanism Using Storage System Determined Write Locations - Mechanisms are provided, in a storage system controller of a storage system, for writing data to a storage medium. The storage system controller receives a write request to write a block of data to the storage medium. The write request does not specify a location on the storage medium to which to write the block of data. The storage system controller determines a current position of a write mechanism of the storage system relative to the storage medium and determines a location on the storage medium to write the block of data based on the current position of the write mechanism. The storage system controller sends a notification to a host system identifying the location of the block of data on the storage medium as determined by the storage system controller. The writing mechanism writes the block of data to the determined location on the storage medium. | 07-10-2014 |
20150098148 | LINEAR RECORDING DEVICE FOR EXECUTING OPTIMUM WRITING UPON RECEIPT OF SERIES OF COMMANDS INCLUDING MIXED READ AND WRITE COMMANDS AND METHOD AND PROGRAM FOR EXECUTING THE SAME - A method is provided according to one embodiment, which executes an optimum writing method even when overwrite is intervened between mixed read and write operations. In response to receiving an overwrite command while executing the mixed operations, which writes to a predetermined tape position, when a tape position to overwrite on is encountered before the append-written data ending position of the tape (tape EOD), the overwritten tape position is regarded as the append-written data ending position of the tape (tape EOD) to update the tape EOD by the overwritten tape position. When a tape position to overwrite is encountered after the append-written data ending position of the tape (tape EOD), the overwritten tape position is updated by the append-written data ending position of a non-volatile memory (non-volatile EOD). The updating the EODs enhances the performance of the mixed read and write operations even when an overwrite command is intervening. | 04-09-2015 |
