Abstract: An information recording apparatus irradiates a recording light, such as a laser light, on a recording medium, such as various kinds of optical discs, and records information. A recording pulse signal is generated based on a recording signal corresponding to the information to be recorded. The recording pulse signal is also called “strategy signal”, and the signal includes driving pulses which drive a light source for forming a recording mark on the recording medium. As to the recording light such as the laser light, the high frequency signal is superimposed for decreasing occurrence of noise due to mode hopping. The high frequency signal is generated as a digital signal, and the signal is added to the recording pulse signal to generate a driving pulse signal. Then, the light source is driven and the recording light is emitted. By generating the high frequency signal as the digital signal, it is possible to control a frequency and a phase thereof with high accuracy.

Abstract: The natural vibration frequency of a roll resonance which does not occur since the engine rotation number is high in a normal operation range of an engine is detected at the time of engine start or stop when the engine rotation number is lower than the normal operation range, and thus the natural vibration frequency of the roil resonance can be detected with a good accuracy. A current is generated by an electromotive force of an actuator of the active vibration isolation support device excited by the engine immediately before stopping its rotation, and the frequency of the current is used to detect the natural vibration frequency of the engine, and the roll resonance of the engine is suppressed by controlling the operation of the active vibration isolation support device at the time of engine start based on the natural vibration frequency, thereby not only eliminating the need of a specific frequency detection sensor, but also effectively reducing the vibration at the time of engine start when the roll resonance becomes strong.

Abstract: A tilt of a light beam to be radiated onto an information recording disk is corrected without using a dedicated tilt sensor. The correction is performed based on the characteristic that an offset amount between a tilt amount maximizing an RF signal amplitude and a further tilt amount maximizing an LPP signal amplitude is constant and independent of positions on the same disk. A pre-pit signal indicative of an existence/nonexistence of a pre-pit formed on the disk is produced from returned light of the light beam, while an RF signal is produced from bits of information recorded on the disk on the basis of the returned light. An optimum tilt-correcting amount is decided by making use of a relationship between the pre-pit signal and the RF signal at a particular tilt amount. The tilt amount is corrected using the optimum tilt-correcting amount.
