摘要:
In a recordable optical disc including at least one recording layer, write strategy information is recorded within disc control information, so that standardized disc control information can be uniformly applied to data recording and reproduction. At least one disc information is recorded as the disc control information within the management area. The disc control informations are recorded for at least one write strategy for a same writing speed and recording layer.

The present invention relates to method and apparatus for interfacing for controlling a device between various applications operated on a home network and a library to ensure their compatibility. In a method for controlling a device on a home network according to the present invention, an application calls a function of a library for controlling a device on a network while providing an identifier of a device to control and a command code for control through a mutually-shared structure, and the library requests a command identified by the command code to a device specified by the identifier and delivers resultant information from the device to the application through the shared structure.

The present invention provides a method for forming a multi-wavelength semiconductor laser device. The method comprises sequentially forming an AlGaAs-based epitaxial layer for a first semiconductor laser diode and an etching stop layer composed of AlxGayIn(1-x-y)P (0≦x≦1, 0≦y≦1) on a substrate and sequentially growing an n-type GaAs flattening buffer layer and an AlGaInP-based epitaxial layer for a second semiconductor laser diode on the substrate, after selectively removing the AlGaAs-based epitaxial layer and the etching stop layer.

Disclosed are an apparatus and a method for controlling a tracking servo in a near field optics. Gap error signals are detected in a divided state, and a push pull signal is compensated based on the detected gap error signals. A photo detector detecting the gap error signals is divided into two areas such that movement of an image formed on the photo detector can be detected. The push pull signal is compensated by subtracting a value proportional to a difference value between the two gap error signals detected in the photo detector. The difference value between the two gap error signals is proportional to a dc offset component included in the push pull signal. Accordingly, it is possible to simply remove a dc offset included in a push pull signal without largely modifying the near field optics, so that it is possible to exactly perform a tracking servo operation.

The present invention relates to a method of enabling to reproduce main AN data recorded on a high-density recording medium such as a Blu-ray Disc ROM at a playback speed suitable to the recorded main A/V data. In the present method, when main video data is recorded on a recording medium, playback speed information suitable to the video data is also written within a disc information table allocated in a control area that is located ahead of a data area including the video data. The present method is efficiently applicable to a high-density recording medium containing higher-quality video data that requires higher transfer rate than a digital TV broadcast stream that requires about 36 Mbps transfer rate.

A clothes drying machine having a sensing switch easily installed on a motor bracket for sensing whether or not a belt for rotating a rotary drum is loose or cut. The sensing switch includes a first insertion hole having a longitudinally extended shape and a second insertion hole having a circular shape, and the motor bracket includes first and second insertion members respectively inserted into the first and second insertion holes. An extended portion of the first insertion member has a size and a shape corresponding to those of the first insertion hole so that the sensing switch is fixed without movement when the first insertion member is inserted into the first insertion hole. A flat portion of the second insertion member is provided with a screw hole formed therethrough so that the sensing switch is firmly fixed to the motor bracket by inserting a screw into the second insertion hole and the screw hole.

Provided are a semiconductor laser diode and a method of manufacturing the same. The semiconductor laser diode includes a lower cladding layer disposed on a substrate; a ridge including an optical waveguide layer, an active layer, an upper cladding layer, and an ohmic contact layer, which are sequentially stacked on the lower cladding layer, and having a predetermined width, which is obtained by performing a channel etching process on both sides of the ridge; an oxide layer disposed on surfaces of the upper and lower cladding layer to control the width of the ridge; a dielectric layer disposed on left and right channels of the ridge; an upper electrode layer disposed on the entire surface of the resultant structure to enclose the ridge and the dielectric layer; and a lower electrode layer disposed on a bottom surface of the substrate. The method is simpler than a conventional process of manufacturing a semiconductor laser diode. Also, by controlling a wet oxidation time, the width of a ridge can be freely controlled and an ohmic contact layer can be automatically formed.
