摘要： 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.
摘要翻译：信息记录装置将诸如激光的记录光照射在诸如各种光盘的记录介质上并记录信息。基于与要记录的信息相对应的记录信号来生成记录脉冲信号。记录脉冲信号也称为“策略信号”，该信号包括在记录介质上驱动用于形成记录标记的光源的驱动脉冲。对于诸如激光的记录光，叠加高频信号以减少由于跳频引起的噪声的发生。产生高频信号作为数字信号，并将该信号加到记录脉冲信号上以产生驱动脉冲信号。然后，驱动光源并发射记录光。通过产生作为数字信号的高频信号，可以高精度地控制频率和相位。

摘要： A groove track and a land track are alternately and spirally formed on an information recording medium. On the land track neighboring the groove track, pre-information indicating position information of a track on a disc is formed as a prepit. On the information recording medium, an embossed area is formed so that information about a copyright and for preventing an illegal copy cannot be rewritten. In the embossed area, an embossed configuration including a pit and a space of predetermined depths is formed. The prepit in the embossed area is formed so that the prepit has an optimized configuration according to a pit length and a space length in the embossed area which the prepit neighbors. Consequently, interference between the embossed configuration and the prepit can be prevented even in a case that the prepit is formed in addition to the embossed configuration in the embossed area.
