摘要:
In optical recording and/or reproduction using an SIL optical system that performs a tilt servo using light for recording and/or reproduction, the SIL and an optical recording medium have a high probability of colliding with each other before the tilt servo is started. To prevent the collision, an optical recording/reproduction method performs a gap servo that controls a gap between a surface of an optical recording medium and a bottom surface of an SIL using reflected light that is generated from light traveling from the bottom surface of the SIL and reflecting on the optical recording medium, a focus servo that controls a distance between a focal point of the light and the bottom surface of the SIL, and a tilt servo that controls a tilt of the bottom surface of the SIL relative to the surface of the optical recording medium using the reflected light. The method includes acts which are performed sequentially: starting the gap servo with the gap being set larger than when optical recording and/or reproduction is performed, and shifting the focal point to an optical recording medium side from the bottom surface of the SIL, starting the tilt servo, and setting the gap smaller and arranging the SIL at a predetermined position.

As a result, servo control can be accurately performed regardless which information layer, out of a plurality of information layers of an optical disc, information is recorded to or reproduced from.

In producing a stamper for molding an optical disc, a master disc which can be obtained from the steps of forming a thermosensitive material layer capable of acting as a negative type by a laser beam on a substrate, irradiating a laser beam to predetermined areas of the thermosensitive material layer so as to partially perform exposure and wet-etching the partially exposed thermosensitive material layer so as to form a fine pits-and-bumps pattern is used as a stamper for injection molding machine. Therefore, minute pits each having a size smaller than the spot of the laser beam of optical limit are formed, thereby providing a stamper with the small number of deficiencies.

The 2D-DST substrate includes a first conductive sheet, a second conductive sheet and a plurality of communication modules. The first and second conductive sheets are overlapped, and the first conductive sheet is located on the subject person side when in use. The plurality of communication modules are distributed between the first and second conductive sheets. At least one of the plurality of communication modules has a communicating system capable of communicating with an external device by receiving and/or transmitting a spatially propagating signal. One of the first and second conductive sheets on the external device side is formed with an area that allows the spatially propagating signal to pass through at a position corresponding to a location of a communication module having the communicating system.
