Patent number: 8032721Abstract: An access control apparatus includes a memory and a command executor executing an access process on a command with the command completion time limit. An address of an inaccessible recording area is stored in the memory. Data attempted to be written on the inaccessible recording area is obtained. The data is stored in association with the address in the memory. An automated alternate processor executes the automated alternate process of the inaccessible recording area in a predefined period of time after the process executed by the command executor is completed. A memory updater deletes the address of the inaccessible recording area whose automated alternate process has succeeded and the data attempted to be written in the recording area at the address.Type: GrantFiled: October 29, 2008Date of Patent: October 4, 2011Assignee: Toshiba Storage Device CorporationInventor: Hiroaki Murai

Patent number: 7603517Abstract: A disk storage device stores write data in a cache area of a data buffer according to a write command from a host, reports write completion to the host, and then writes the write data in the cache area to a storage medium. The disk storage device stores the write data stored in the data buffer in a save area created on the storage disk in response to the reception of a command which requires integrity, other than a write command, and reports a response to the host. Therefore processing time of this command and response time to the host can be decreased, while maintaining the safety of the write data.Type: GrantFiled: September 27, 2005Date of Patent: October 13, 2009Assignee: Fujitsu LimitedInventors: Noriyuki Sato, Hideaki Tanaka, Tatsuya Haga, Shigeru Shimizu, Takumi Kakuya, Yuichi Hirao, Masami Aihara, Hiroaki Murai, Masaki Obuchi, Mitsuhiko Sugiyama

Patent number: 7389378Abstract: A medium storage apparatus writes data for stream type commands on a medium, and improves the reliability of the write data while maintaining the execution time of the commands. The apparatus has a buffer for storing the write data of the write stream type commands, a controller for sequentially writing the data of the buffer to the medium by a head, and a processing unit for skipping the writing of erred sectors for continuing the processing which normally ends if an error occurs, and writing the data to the skipped sector after command execution. By this, the error is corrected such that the medium is correctly read in the next and later read processing, while maintaining the write time specified by the command.Type: GrantFiled: February 27, 2004Date of Patent: June 17, 2008Assignee: Fujitsu LimitedInventors: Hiroaki Murai, Yoshinori Inoue, Satoru Fukase, Takehiro Ogawa

Patent number: 7382559Abstract: A medium storage device reads device specific information from a medium to a memory and performs read/write operation to the medium, which allows receiving commands from a host even if a read error of the device specific information occurs. When an error occurs during the device specific information read processing of the medium storage device after power ON, the alternate data stored in the medium is developed so as to recover the power ON error artificially. For this alternate data, the data at factory shipment is saved in a ROM or a system area of a medium in advance, and is developed from here when necessary. Since commands can be received and executed, a disabled startup of the host system can be prevented.Type: GrantFiled: June 27, 2005Date of Patent: June 3, 2008Assignee: Fujitsu LimitedInventors: Takehiro Ogawa, Yoshinori Inoue, Hiroaki Murai, Satoru Fukase

Patent number: 7239468Abstract: After the power supply of a disk drive that uses a head to write data at any position on a disk or read data written at any position is turned on, the first initial conditions for the disk drive that are needed to receive a command from outside and execute the command are determined. The disk drive is then brought to a state in which it can receive the command but the spindle motor is not started. After the disk drive is brought to the state in which it can receive the command, the spindle motor is started and the second initial conditions including all initial conditions other than the first initial conditions are determined. Moreover, a control method for a disk drive that is implemented in the above disk drive is disclosed.Type: GrantFiled: November 23, 2004Date of Patent: July 3, 2007Assignee: Fujitsu LimitedInventors: Hiroaki Murai, Yoshinori Inoue, Takehiro Ogawa, Satoru Fukase

Publication number: 20060218342Abstract: A media storage device reads device-specific information from media into memory and performs read/write operations to and from media. In an idle loop after turning on power to a media storage device, a MPU performs processing to update device-specific information while command processing is not being performed, preventing loss of device-specific information due to a sudden cutoff of power. The MPU reads the updated device-specific information from the media while command processing is not being performed, to execute read tests.Type: ApplicationFiled: September 1, 2005Publication date: September 28, 2006Inventors: Takehiro Ogawa, Yoshinori Inoue, Hiroaki Murai, Satoru Fukase

Patent number: 5063398Abstract: A color image recording apparatus records a composite color image composed of a plurality of superimposed images of different colors on a recording medium. Each latent image represented by an image signal is formed in a first image recording medium on the recording medium, and then another latent image is formed in a second image recording medium, following the first image recording area, of the recording medium. Then, the latent image in the first recording medium is developed into a visible image by a developing unit with a developing solution containing toner particles of one color. When the recording medium is fed along, toner particles in any residual developing solution left in the developing unit are attracted to the latent image in the second image recording area of the recording medium.Type: GrantFiled: March 6, 1991Date of Patent: November 5, 1991Assignee: Matsushita Graphic Communication Systems, Inc.Inventors: Hiroaki Murai, Tatsuya Katano, Shigeki Kikuchi
