摘要： A library is referred to and thus facilities are executed when executing an application program for receiving and transmitting radio signals. That is, the library serving as programs depending on hardware converts commands based on the application program into signal to control the hardware. As a result, the application program is describable by a program independent of an analog device for receiving and transmitting the radio signal, and a common application program can be used even in case of different hardware.

摘要： A high-density disk unit and disk medium are disclosed. Track ID information is not placed in a servo area, or if some track ID information is placed therein, a necessary minimum is placed. The servo area is thus reduced in order to improve formatting efficiency.A data side of a disk medium is divided into a servo area and a data area in units of a sector. A track ID area in which track information is recorded is defined at the start position of the data area immediately following the servo area. A formatter circuit allows a write data modulation circuit to write track information in the track ID area during track formatting. For writing in the data area, the formatter circuit allows a read data demodulation circuit to read data from the track ID area. Track information is thus detected, and writing tracking is assured.

摘要： An orthogonal demodulating section converts the frequency of received signals to the lower range after rejecting an image band thereof by an RE filter. An image rejecting section rejects the image band of the orthogonally converted output. It allows enough of an 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.

摘要： 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. In the radio apparatus, a transmission power detecting portion is structured as an IC chip. The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground. Thus, when the power is detected, a power loss is suppressed. Consequently, the power consumption of the radio apparatus can be decreased.

The disk apparatus also includes at least one common power unit having a pluralities of batteries attached thereto connected in common with the two systems. Patrol control means (PC) is operatively connected to a power control unit (0) of one system and a power control unit (1) of another system for giving a control signal during a battery monitoring operation and a priority order to the battery monitoring operation. The patrol control means monitors the function of the common batteries attached to the common power unit and, further, when the common batteries are incorporated in the magnetic disk apparatus, controls the simultaneous monitoring of the common batteries and the time of incorporation of the common batteries into the magnetic disk apparatus. When one of the at least two systems is monitoring the common batteries, the power control unit of the one of the at least two system sends a master signal MAS to the patrol control means (PC) indicating that the one of the at least two systems is monitoring the common batteries, and the patrol control means sends an other-system patrol signal O-TST to the other of the at least two system indicating that the one of the two at least two system is monitoring the common batteries.
