A multiroom air conditioner has a plurality of indoor heat exchangers connected to a single outdoor heat exchanger. A reversible expansion valve is installed on a liquid-side branch pipe for each of the indoor heat exchangers, and a solenoid valve is installed on a gas-side branch pipe for each indoor heat exchanger. Temperature sensors are provided on the liquid-side branch pipes, on the gas-side branch pipes, and on the outlet side during cooling of the outdoor heat exchanger. A pressure sensor or a temperature sensor detects the saturation temperature on the high-pressure side of the compressor. Based on the saturation temperature on the high-pressure side of the compressor, the temperature on the outlet side during cooling of the outdoor heat exchanger, and the temperatures in the liquidside branch pipes, a controller controls the expansion valves so as to obtain a target degree of subcooling during cooling and heating. The controller can also control the expansion valves so that the temperatures in each of the branch pipes are approximately equal to one another.

The controller includes a deflection signal generator for generating a deflection signal for causing the electron beam to deflect and perform overwriting so that a beam spot of the electron beam follows the translation of the substrate over a period during which the substrate is rotated over a predetermined number of overwriting cycles; and a data output unit for outputting the drawing data, wherein, the deflection signal generator generates a deflection adjustment signal for irradiating the electron beam at a starting position for drawing a concentric circle to be subsequently overwritten after a predetermined deflection adjustment period has elapsed since overwriting of concentric circles based on the drawing data has completed.

Recording capacity per layer is detected from a disc and bit allocation of wobble addresses in a conventional optical disc and bit allocation in a high-density optical disc are controlled selectively to detect physical position addresses on the disc. Address detection can be performed for two kinds of discs which are equal in structure of addresses embedded in wobbles but different in bit allocation of addresses.

A technique for investigating differences of composition and structural state of a recording layer of an optical disc along with other defects, such as scratches, contamination, warp and distortion, prior to video recording and for setting up appropriate recording conditions in compliance with this result to thereby perform recording is disclosed. In an optical disc recording device capable of recording information on an optical disc, a region to be investigated is defined based on the video recording reservation contents. Then, investigate and evaluate the disc state which can affect the recording quality in a target disc region to be recorded. Next, based on investigation/evaluation results, perform recording setup, recording speed setup, servo control setup and recording position setup to thereby perform the recording. By appropriately modifying the recording setup on a case-by-case basis, it is possible to achieve high-quality recording.

A method for reproducing information on a dual layer disc which has two recording layers including layer 0 and layer 1 reproducible from one side of the [disk] disc, wherein each layer has a plurality of sectors. The method includes the steps of emanating an optical beam from a laser source, concentrating the optical beam on a recording layer with an objective lens, moving the objective lens in the direction of the thickness of the [disk] disc so that a focal point of the objective lens is focused on one layer of the two recording layers, obtaining a present layer information of a sector of the recording layer being reproduced from the reflected light from the [disk] disc, confirming a target layer information of a target recording layer of a target information, and moving the objective lens in a direction of the thickness of the [disk] disc until the focal point of the objective lens is focused on layer 1 when the present layer information is layer 0 and the target layer information is layer 1.
摘要:
An apparatus for controlling the rotation of a motor to rotate a recording medium where an information signal and synchronizing signal are recorded. In such motor rotation control, normally the synchronizing signal reproduced from the recording medium is phase-compared with a reference synchronizing signal, and the motor rotation is so controlled as to eliminate the phase error between the two compared signals. And upon occurrence of any great variation in the motor rotation due to information dropout or the like on the recording medium, such variation is detected, and a rotational frequency signal obtained from a rotational frequency detector is phase-compared with a reference frequency signal generated on the basis of the data relative to the motor rotational frequency stored sequentially in a memory. Then the control mode is switched for controlling the motor rotation in such a manner as to eliminate the phase error between the two compared signals, whereby the problems including runaway of the motor and so forth can be solved.
