An information recording and reproducing apparatus (S) is provided with: a first reproducing device () for reproducing audio information from a first information record medium (DK), in which the audio information is recorded; a recording device () for recording the reproduced audio information into a second information record medium (HD); a second reproducing device () for reproducing the audio information recorded in the second information record medium; and a controlling device () for setting a recording speed when recording the audio information into the second information record medium and a reproducing speed when reproducing the audio information from the second information record medium such that the recording speed is equal to or higher than the reproducing speed, and controlling the second reproducing device and the recording device so as to perform reproducing the recorded audio information from the second information record medium at the set reproducing speed in parallel to recording the audio information into the second information record medium at the set recording speed.

Apparatus for and method of recording and reproducing information

A medium is set in a computer, and identification information of the set medium is read out. Related information about the medium is obtained in accordance with the identification information read from the medium. The obtained related information is displayed on a display.

Computer for a reproducing medium

System for processing information which reads address information

A contents presenting system includes: an analyzing unit which collects and analyzes user's conversation to output an analysis result; a contents acquiring unit which acquires contents from a contents database based on the analysis result; and a contents presenting unit which presents the acquired contents to the user. Since the analysis result of user's conversation includes a factor representing the environment where the user is talking, by determining contents based on the analysis result, it is possible to provide the contents which is suited for the environment where the user is present.

Contents presenting system and method

In a disk drive apparatus for forcibly restoring a head to a retract position when a power voltage is greatly lowered, the head is moved in a direction toward the retract position when detecting a small decrease in the power voltage.

A navigation information updating system G updates navigation information for use in a navigation process executed by navigation apparatus S that navigate respective vehicles. The navigation information updating system G comprises: the navigation apparatus transmitting an identifier Sid associated therewith to an updating center UC; the updating center UC that outputs updated navigation information which is generated on the basis of the transmitted identifier Sid for each associated navigation apparatus S, to a shop SP; and the shop SP that delivers the outputted updated navigation information to the associated navigation apparatus S.

System for updating navigation information and apparatus for distributing updated navigation information

A navigation system is provided that allows an appropriate destination point to be set when a vehicle begins to travel without an operator setting a destination point. A navigation system is provided with a system control section and, if a vehicle begins to travel without an operator setting a destination point, destination point information is retrieved. This destination point information is stored in a travel information database on the basis of information about the position of the vehicle, the direction in which the vehicle is progressing and information about the road. The road is which the vehicle is traveling along that was calculated based on the respective signals input from a GPS receiving section and various sensor sections. In addition, if there are candidates for the relevant destination point, candidate destination points are displayed on a display section as predicted destination points.

Navigation system, server system for a navigation system, and computer-readable information recorded medium in which destination prediction program is recorded

A disk drive device in which emergency unloading at the start of the engine is prevented, a head may have a prolonged life and improved reliability as an HDD is achieved. A disk drive device is driven or the movement of a magnetic head is allowed after an engine start in a vehicle is detected by an engine start detecting part, so that emergency unloading can be prevented at the start of the engine. In order to detect the engine start, voltage values on four power supply lines for a vehicle power supply device are monitored or the outputs of various sensors such as a tachometer, a vibration detection sensor, an engine sound detection sensor, a vehicle speed pulse, a gyro sensor and a parking brake are monitored. In another embodiment, the number of emergency unloading occurrence at the start of the engine is reduced, which allows the head to have a prolonged life, so that the disk drive device has improved reliability as an HDD. The voltage values on two power supply lines, first and second power supply lines for a vehicle power supply device are monitored. The magnetic head is allowed to move when the voltage values on the first and second power supply lines attain a prescribed value after a prescribed time period after the voltage value on the first power supply line attains prescribed value.

Disk drive device

The digital signal conversion apparatus comprises: an over-sampling circuit that samples the input digital signal at high frequency; a polarity-inversion circuit that inverts the polarity of the sampled digital signal; interpolation circuit (A) and interpolation circuit (B) that perform interpolation of each respective digital signal; noise-shaping circuit (A) and noise-shaping circuit (B) that perform noise shaping on the interpolated signals; PWM conversion circuit (A) and PWM conversion circuit (B) that perform PWM conversion on the noise-shaped signals; and a switching circuit for driving a load based on the PWM signals from PWM conversion circuit (A) and PWM conversion circuit (B).
