Abstract: PURPOSE: To reduce the noise generated in a driving system by a method wherein the speed of the movement of a recording-reproducing part to the direction of the radius of a disk-shaped recording medium is made smaller in recording than that in reproduction. CONSTITUTION: In the case of recording, a system controller 19 discriminates whether a mode is stereophonic or monophonic, on the basis of a signal from a terminal 66. According to a drive signal from a loading motor control circuit 22 generated on the basis of a control signal corresponding to the mode, a loading motor 14 makes a magnetic head 28 move to a position in proximity to an optical disk 12. A servo circuit being switched over by a switch simultaneously, the speed of rotation of a feed motor 21 is controlled to be about 1/2 or 1/3 of that at the time of a reproducing operation, corresponding to the monophonic or stereophonic mode, and thereby the speed of movement of a pickup 15 and the magnetic head 28 in the direction of the radius of the disk is decreased by a feed mechanism using a feed motor 21 as a drive source. By this constitution, the noise generated in the feed mechanism using the feed motor 21 as the drive source can be reduced.

Abstract: PURPOSE: To properly judge the detection of a battery capacity corresponding to the recording time or the reproducing time and to contrive elongation of a battery lasting time and also miniaturization and weight reduction of the equipment concerned. CONSTITUTION: A voltage of the battery 33 is fetched into a system controller 11, where judgement is performed as to whether a battery capacity is enough or not. At the time of judging the battery capacity, detecting width of the battery voltage is changed for the recording time and the reproducing time. Consequently, judgement as shortage of the capacity is prevented from happening for a battery which still has remained capacity at the recording time, due to an effect of a temporary drop of the battery voltage at the time of starting intermittent recording.

Abstract: PROBLEM TO BE SOLVED: To perform recording without sound distortion at an appropriate level corresponding to the line-output level (2 Vrms) of stationary audio devices and the line-output level (approx. 0.775-1 Vrms) of portable audio devices. SOLUTION: The user can select either one of the two line-input modes, the 1st mode corresponding to the line-out level of approx. 0.775-1 Vrms and the 2nd mode corresponding to the line-out level of 2 Vrms. When the 2nd mode is selected, the audio signal gain (level) is reduced by the variable gain amplifier composing the line-input circuits or the AGC circuit. Or a clearance is maintained between the AGC limit level and the maximum input level by lowering the limit level of the AGC. Alternatively, the distortions are hardly made even at steep attacks by shortening the attack time of the AGC processing. COPYRIGHT: (C)2006,JPO&NCIPI

解决方案：用户可以选择两种线路输入模式之一，第一模式对应于大约的线路输出电平。 0.775-1 Vrms，第二模式对应于2 Vrms的线路输出电平。 当选择第二模式时，由构成线路输入电路或AGC电路的可变增益放大器减小音频信号增益（电平）。 或者通过降低AGC的限制电平，在AGC极限电平和最大输入电平之间保持间隙。 或者，即使在陡峭的攻击下，也不能通过缩短AGC处理的攻击时间来实现失真。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To continuously provide supply voltage only to a memory, in which disk management information is stored, in a sleep state with a remarkably simplified circuit configuration without using a special logical circuit. SOLUTION: The disk drive device is equipped with a sub power circuit 24 for providing the supply voltage to the memory, in which the disc management information is stored, even in the sleep state. In a sub power circuit 25, a diode 28 is connected between an output terminal (VDD_2) and a chip enable terminal (CE). When a main power circuit 24 is turned off and switched to the sleep state, a system controller 17 halts operation for the main power circuit 24 after this chip enable terminal (CE) is switched to a high level.

Abstract: PROBLEM TO BE SOLVED: To suppress distortion of a reproducing sound at the time of adjusting a low-frequency sound in the sound reproducing device such as an MD(minidisk) reproducing device, etc., without causing a raise in the cost of the device. SOLUTION: A digital sound signal modulated by an RF signal from an optical head 3 is supplied via an RF amplifier 5 to a DSP(digital signal processor) 6 to be processed. The digital sound signal from the DSP 6 is supplied to a D/A converter 7 to be converted into an analog sound signal. A low-frequency sound adjusting switch 11 is capable of a changeover among three positions of 0, 1 and 2, and when the changeover is made to the position 0, the low-frequency sound adjustment is turned off in the D/A converter 7, and an instruction of a normal sound volume is issued to the DSP 6 by a system control part 10. When the low-frequency adjusting switch 11 is switched over to the position 1 or 2, the low-frequency sound is strengthen to raise its level by about 4 dB or about 9 dB at 100 Hz in the D/A converter 7, and simultaneously, the DSP 6 is instructed to lower the sound volume by 2 dB by a system control part 10, and hence the sound volume is lowered by 2 dB over the whole frequency band by the DSP 6.

Abstract: PROBLEM TO BE SOLVED: To eliminate the inconveniences caused by the level differences between music pieces and the environments when reproducing. SOLUTION: A level conversion mode (reproduction compressor mode)is provided to compress the dynamic range of the reproduced audio signals. The user operates to select ON or OFF of the level conversion mode. A compression operation to linearly compress the dynamic range in the level conversion mode is performed when it is set on. Alternatively, the level difference between the musical pieces is reduced with less dynamic range compression of the music itself in the gain control. COPYRIGHT: (C)2006,JPO&NCIPI
