Patent number: 7818556Abstract: Firmware FW1 and FW2 is separately stored in a non-volatile memory, in which a boot code for start-up and a restoration code are stored, and a first magnetic disk. A copy of the firmware FW1 stored in the non-volatile memory is stored in the first magnetic disk, and a copy of the entire firmware FW1 and FW2 stored in the first disk medium is stored in the second magnetic disk. When an error occurs during firmware update, upon next power-on, whether the volatile memory, the first magnetic disk, and the second magnetic disk are normal or abnormal is determined, and valid firmware is read and allocated to the volatile memory so as to perform start-up by a start-up mode corresponding to the determination contents.Type: GrantFiled: July 25, 2007Date of Patent: October 19, 2010Assignee: Toshiba Storage Device CorporationInventors: Hirotaka Iima, Hiroshi Tsurumi, Masataka Shitara, Katsushi Ohta, Masaaki Tamura, Yasuyuki Nagashima

Publication number: 20100191905Abstract: A storage device comprises a recording/reproducing module which positions a head at an arbitrary position of a storage medium to record or reproduce data and a nonvolatile memory in which a parameter storage area is defined. An adjustment module adjusts various types of parameters necessary for controlling a positioning control module and the recording/reproducing module. A parameter save processing module saves adjusted parameters obtained by the adjustment module in the nonvolatile memory during adjustment, while leaving the minimum number of the adjusted parameters necessary to access a system area of the storage medium at the end of the parameter adjustment, and saves the remaining adjusted parameters in the system area of the storage medium to form a free area in the parameter storage area of the nonvolatile memory. The free area processing module uses the free area of the nonvolatile memory as a storage area for firmware, a log or the like other than the parameters.Type: ApplicationFiled: July 6, 2007Publication date: July 29, 2010Applicant: TOSHIBA STORAGE DEVICE CORPORATIONInventor: Hiroshi Tsurumi

Patent number: 7590400Abstract: In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state. In addition, a radio wave environment is measured. A characteristic necessary for the radio apparatus is determined corresponding to the measured-radio wave environment. The power is controlled corresponding to the performance of the radio apparatus. Thus, the power consumption is decreased. In addition, the efficiency of the output power is improved. In the radio apparatus, the current consumption of a power amplifier PA is measured. A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss. In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave. When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process.Type: GrantFiled: January 9, 2007Date of Patent: September 15, 2009Assignee: Kabushiki Kaisha ToshibaInventors: Shoji Otaka, Hiroshi Tsurumi, Hiroshi Yoshida, Syuichi Sekine, Hiroyuki Kayano, Tadahiko Maeda

Publication number: 20080040818Abstract: A storage apparatus divides and stores firmware which is drive control software to record and reproduce data in a disk medium into a non-volatile memory and a disk medium, and at the time of activating the apparatus, stores and executes firmware read from the non-volatile memory and the disk medium into a volatile memory. A renewal request processing unit, when received a renewal request of the firmware from a host, advises the host of the renewal completion at a point of time when new firmware transferred from the host is received and stored in the buffer memory. The background renewal unit, after the advice of the renewal completion, writes and renews the new firmware into the non-volatile memory and the disk medium as a background processing using the processing idle time of a command issued by the host.Type: ApplicationFiled: December 8, 2006Publication date: February 14, 2008Inventors: Hirotaka Iima, Hiroshi Tsurumi, Masaaki Tamura, Masataka Shitara
