摘要： A probe (6) is displaced relative to a recording medium (8) according to a drive voltage. A chip (7) is provided at an end of the probe (6). The chip (9) serves to form pits and projections on a surface of the recording medium (8) according to a recording voltage (Vp2) and serves to output a current signal responsive to the pits and projections with a reproducing voltage (Vp1) applied. A voltage generator (14, 15) generates the recording voltage and the reproducing voltage based on address and data signals. A sample-hold unit (20, 21) samples at a specified frequency a current signal obtained from a no-recording area (9) of the recording medium by the chip (7) and produces an output voltage signal. A reproducing unit (16) demodulates and reproduces increment and decrement of the current signal obtained from a recording area (10) of the recording medium by the chip (7). A control unit (22) controlles recording and reproduction. The control unit outputs such a drive voltage that the interval between the chip (7) and the recording medium (8) is maintained constant by feedback control based on the voltage signal derived from the sample-hold unit (20, 21). The control unit controlles the recording so that no-recording areas (9) and recording areas (10) are arranged alternately.

摘要： The optical recording medium driving apparatus has a first high-pass filter (22) for outputting a low frequency component removed signal by removing a low frequency component from a reproduction signal varying depending on a reflected light beam from the optical recording medium (1). The low frequency component removed signal changes due to transient response just after an access operation starts. Zero voltage is input to a second high-pass filter (28) during a tracking operation while a voltage having a negative polarity which is substantially the same amplitude as the AC component of the low frequency component removed signal is input to the second high-pass filter (28). The first high-pass filter (22) has the same time constant as the second high-pass filter (28). Just after the access operation starts, the negative voltage has the same transient response as the output of the first high-pass filter (22). The output of the first high-pass filter (22) is compared to the output of the second high-pass filter (28) in order to have a binary signal of a binary logic condition. A land is discriminated from a groove according to the binary signal, thereby enabling accurate access to a target track.

摘要： In an optical recording medium driving apparatus, only a frequency component corresponding to pits of an ID portion (4) is detected from a total signal representing a total amount of reflected light from an optical disc (1) by a high pass filter (30). With this frequency component clamped so that a potential at a maximum point becomes a definite potential, a changed amount of light of the total signal corresponding to pits is detected and a phase pit signal is generated. In response to this phase pit signal, a signal component corresponding to pits is removed from the total signal, thereby generating a pit removal signal.

摘要： In the optical recording element of the invention, alignments of long thin pits inclined in various directions with respect to the track direction are formed on the tracks and information is recorded therein according to the different inclines of the pits, thereby performing higher-density and larger-volume recording without reducing the spacing between each pit and the track pitch.
The invention also discloses an optical data retrieval system for use with the above optical recording element, which scans the pit alignments with a laser beam spot, detects the inclines of the pits by obtaining the distribution of the intensity of reflected light which is caused by light diffraction at the pits, and plays back information in accordance with the inclines. Therefore, not only can the substantially same structure as that of a standard type optical data retrieval system be applied to the invention without making any complicated change, but also cross-talk is less likely to be produced in the read out signals.摘要翻译： 在本发明的光记录元件中，在轨道上形成在各个方向上相对于轨迹方向倾斜的长细孔的排列，并且根据凹坑的不同斜度记录信息，由此执行更高密度和更大的 - 音量记录，而不减少每个凹坑和轨道间距之间的间距。 本发明还公开了一种与上述光学记录元件一起使用的光学数据检索系统，其利用激光束点扫描凹坑对准，通过获得由光引起的反射光强度的分布来检测凹坑的倾斜 在凹坑处衍射，并根据倾斜回放信息。 因此，不仅可以将本质上与标准型光学数据检索系统基本相同的结构应用于本发明，而且不会发生任何复杂的变化，而且在读出信号中也不太可能产生串扰。

A nozzle plate (10) having a nozzle orifice (11), and a substrate (7) constitute part of a peripheral wall of an ink chamber (31). A pressure generating member (20) is provided in the ink chamber (31). The pressure generating member (20) has a buckling member (1), a heater layer (3), and a diaphragm (5). The buckling member (1) is formed into a generally plate shape and its peripheral portion is attached to the substrate (7). The buckling member (1) can be switched between a no-displacement state in which it undergoes substantially no thermal stress, and a buckled state in which it is thermally expanded and buckled. The heater layer (3) is provided along a surface of the buckling member (1) on the substrate (7) side. The diaphragm (5) is composed of a generally plate-shaped flexible material and provided along a surface of the buckling member (1) on the nozzle plate (10) side in such a state that at least its peripheral portion (5c) is attached to a peripheral portion (1c) of the buckling member (1).
