摘要： An optical pick-up according to the present invention is designed such that laser beams having different polarization directions or different radiation angles are irradiated from laser beam sources formed in a surface emitting laser array to change the effective numerical aperture of an optical element having an objective lens, or the like. An optical pick-up having high capability with an optical disk having a low recording density and a thick substrate according to the CD standard, and an optical disk having a high recording density and a thin substrate according to the DVD standard, can be realized. A plurality of laser beam sources can be formed in a small space by employing a surface emitting laser array, and the numerical aperture of the optical system can be controlled by selecting a laser beam. For this reason, an optical pick-up having compatibility can be realized with an extremely simple arrangement, and a compact and high-performance optical pick-up can be provided at low cost.

摘要： A liquid storage unit for collecting a liquid supplied to an ejecting head is provided. The liquid is supplied to a plurality of ejecting heads via a pressure regulating valve, and the liquid is suctioned from the plurality of ejecting heads by a circulation pump, and then is discharged to the liquid storage unit. In this way, since the liquid is suctioned from each of the ejecting heads, the passage resistance is decreased, so that the ink can be appropriately circulated. In addition, since the ejecting head is supplied with the liquid at an appropriate pressure from the liquid storage unit via the pressure adjusting valve, the liquid can be appropriately ejected.

摘要： A laser emission unit for use in an optical head performs a plurality of functions which are integrated. A laser beam from the laser emission unit mounted in a lens holder is emitted through an objective lens and is focused on an optical medium. A reflected beam from the optical medium returns through the objective lens and a diffraction grating to a signal detection circuit in the laser emission unit. Since the laser emission unit performs a plurality of functions, the space for various elements otherwise required in the optical head can be eliminated. The space for an additional light path for the reflected beam is also eliminated. Therefore, the size of the optical head is very small. Since the optical head can be assembled by using a small number of parts, the production costs can be reduced. Furthermore, the optical head can shield the noises by using the housing and/or the lens holder itself.

摘要： A plurality of inclined planes (1419) are formed in the same substrate (1406) and a polarizing optical thin film is provided on these inclined planes. These inclined planes are filled with a transparent material so as to form a small sized and complexed polarizer. This polarizer is excellent in transmission ratio and in extinction ratio. With this polarizer, it is possible to detect a magneto-optical signal with a high signal-to-noise ratio. This polarizer is used as a cover of a package (1408) of an optical head in which a light receiving device (1410, 1411) and a light emitting device (1409) are contained in the form of a single piece. There is also provided an optical element capable of adjusting optical paths so that the optical length of a returning optical beam may be different from the optical length of a forward optical beam. With this optical element, it becomes possible to delete the initial offset in a focusing error signal, and thus adjustment process becomes unnecessary. With these arrangements, it is possible to achieve the size reduction, simplification, and improvement of performance associated with an optical head for use in a magneto-optical recording/reproducing device.

摘要： An integrally-driven type optical head (1) in which a laser optical system (20) provided with a semiconductor laser (22) and a light receiving device is mounted in a moving part of an actuator (50). In this optical head, the moving part (5) is constituted by uniting a heat radiator (10) made of a metal or the like with a heat insulator (9) made of a plastic or the like. The heat conduction bonding of the heat radiator to the semiconductor laser is performed. A coil of the actuator is securely fixed to this heat radiator through the heat insulator. Thereby, heat generated from the semiconductor laser is transferred to the heat radiator and is then radiated from the surface of the heat radiator to the external space of the optical head. Further, in case where heat is generated by the coil when the actuator operates, the laser optical system can be prevented from being heated, because of the fact that the heat conductivity between the coil and the laser optical system is low. Moreover, an increase in weight of the head, which is a hindrance to an operation thereof, can be prevented. Simultaneously with this, the rigidity of a holder can be increased. Thus an occurrence of harmful resonance can be prevented during the actuator is driven. Therefore, the heat radiation/cooling characteristics of the semiconductor laser can be considerably improved. Consequently, a stable operation of the apparatus and the reliability thereof can be achieved.

摘要： By using a semiconductor laser of a relatively long wavelength relative to the track pitch of an optical recording medium, and the optical super-resolution technique, there are provided an optical head and an optical recording apparatus which permit processing such as recording and regeneration onto and from a conventional CD-R with no problems, and processing of an optical recording medium of the DVD standard with a high recording density. In the optical head and the optical recording apparatus of the present invention, a semiconductor laser having a relatively long wavelength relative to the track pitch of an optical recording medium can be used. The invention therefore provides an optical head and an optical recording apparatus which overcome the limit on efforts toward a higher density, and permit recording and regeneration at a high recording density at a low cost with a high reliability. The invention provides also an optical head and an optical recording apparatus capable of coping with the tendency toward a higher density in the future.
