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.

摘要： 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.

摘要： An object of the present invention is to minimize an overhead attributable to internal control and to provide a CDR type disk unit in which even when a head moves over a zone boundary, a sector pulse indicating a destination sector can be generated reliably without waiting for an index pulse. The disk unit includes a processing unit; a sector pulse generation unit which generates a sector pulse according to a signal written in the servo information on medium surface; and a format control unit which starts the formatting control when said sector pulse is received after a activating command is received from said processing unit; a target sector detection unit which detects the instant when said head reaches the target sector. The sector pulse generation unit stops outputting the sector pulses to the format control unit from when the access operation starts until a target pulse is received from the target sector detection unit.

摘要： A filter control apparatus which controls a frequency variable filter capable of changing a transmission band width by controlling a capacitance of at least a portion of a plurality of voltage variable capacitors connected in series and parallel to a resonator has an input unit, and a filter control circuit. The input unit inputs a reference signal with a predetermined reference frequency to the frequency variable filter. The filter control circuit controls a center frequency and the transmission band width of the frequency variable filter by detecting a phase change generated when the reference signal passes through the frequency variable filter and by variably controlling the capacitance of at least a portion of the voltage variable capacitor by using a direct voltage in proportion to the phase change.

摘要： An orthogonal demodulating section converts the frequency of received signals to the lower range in batch after rejecting an image band thereof by an RF filter. An image rejecting section rejects the image band of the orthogonally converted output. It allows an enough image rejecting degree to be obtained. An A/D converter section converts the whole range into a digital signal and an orthogonal demodulating section demodulates a desirable channel by means of digital processing. Then, a channel selecting section selects and outputs the desirable channel. It then allows wide-bands to be received in batch, flexible processing to be achieved by the digital processing and an enough image rejecting degree to be obtained.

摘要： A variable-gain amplifier circuit has an offset correcting function by which the fluctuation of offset due to the switching of a gain is decreased. In an offset detection mode, an input offset voltage of the variable-gain amplifier circuit is inputted to an offset retaining section, and in a signal amplifying mode, the offset is corrected by subtracting the output of the offset retaining section from an input signal by means of an input section of the variable-gain amplifier circuit. In addition, the variable-gain amplifier circuit can be applied to a radio receiver. The offset produced in a baseband section of a receiver is corrected by the offset correcting function of the variable-gain amplifier circuit, so as to prevent the quality of communication from being deteriorated.
