Abstract: PROBLEM TO BE SOLVED: To equalize the quality of reproduced signals when playing back each signal surface of a two-layered optical disk on which high density and one side reading is performed. SOLUTION: A first signal plane 2, 42, a semitransparent film 4, 44, an intermediate layer 6, 46, a reflective film 10, 50, and a 2nd signal layer 8, 48 are deposited sequentially to produce a two-layered optical disk of one side reading type which has signal pits on the semitransparent film side of the 1st signal layer 2, 42 and on the reflective film side of the 2nd signal layer 8, 48, respectively.  The thickness of the 1st signal plane 2, 42, the opening NA of a reproducing head H, or the wavelength of a laser beam is selected suitably, and jitters when reproducing each signal pit of the first and second signal planes 2, 42, 8, and 48 are approximately equated so that the focal point FP where the read laser beam is most converged is set in the intermediate layer when a read laser beam from a reproducing head H is entered from the 1st signal plane side approximately vertically onto the two-layered optical disk of one side reading type.

Title: Horizontal width correction circuit and television receiver
Inventor: KURIAKI MAKOTO
IPC: H04N3/223
Filed: 2001-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a television receiver provided with a horizontal width correction means with less wasteful power consumption at a low cost.  <P>SOLUTION: A beam current detection circuit 5 outputs a voltage V1, which is lower as a beam current is higher. As the voltage V1 is lower, a collector current Ic of a transistor 61 is smaller. As the collector current Ic is smaller, a voltage drop across a resistor 65 is smaller. A voltage Vb of a wire 100, that is, a voltage applied to a horizontal deflection high voltage generating circuit 2 is lower as the collector current Ic is smaller. Since horizontal deflection power is smaller when the voltage Vb gets lower, the horizontal width is also smaller. That is, in the absence of a horizontal width correction circuit 6, the horizontal width gets greater as the beam current is increased. Meanwhile, the voltage Vb applied to the horizontal deflection high voltage generating circuit 2 is lower as the beam current is increased by the operation of the horizontal width correction circuit 6 to thereby suppress the horizontal width.  <P>COPYRIGHT: (C)2003,JPO
