Title: Method for initializing phase change optical disk, and phase change optical disk
Inventor: KASAMI YUTAKA
IPC: G11B7/0055
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress the increase in a jitter value by setting the space length between marks at a length below the shortest space length between the information signals to be recorded afterward at the time of crystallizing the recording region of a disk and recording the marks along tracks by irradiating this region with light at the time of initialization. SOLUTION: The multifilm layers including the phase change material layer and reflection layer deposited on a transparent substrate having the tracks consisting of grooves 3 and lands 4 make information signal recording surface in this phase change optical disk 10. This information signal recording surface is crystallized by suing an initialization device as an initialization stage, by which spaces 1 are formed and the signals of the space length SL below the shortest space length of the information signals are recorded with a mark 2 in the grooves 3 along the tracks. Since the marks 2 are recorded in the grooves 3 by amorphous materials having low reflection, the pull-in level of the initialized phase transition optical disk 10 falls. As a result, the increase in the jitter value of about several times of overwriting is suppressed.

Abstract: PURPOSE:To prevent any deterioration of a phosphor layer formed on the inner surface of the outer tube which might be caused by ultraviolet ray by installing an ultraviolet-shielding member which does not transmit ultraviolet rays with a wavelength of below a given level between the emission tube and the phosphor layer. CONSTITUTION:An emission tube 4 in which mercury, argon gas, a metal halide and electrodes 5a and 5b are sealed, is installed in an outer tube 1 which is charged with nitrogen gas and in the inner surface of which a phosphor layer 2 is formed thereby constituting a metal halide lamp. A light-transmitting shielding member 9 which does not transmit ultraviolet rays with a wavelength of below lambda, is insalled outside the emission tube 4: lambda should satisfy the formula lambdaIB<lambda< lambdaFL when the maximum wavelength for ultraviolet rays not transmitted by the emission tube 4 is supposed to be lambdaIB(nm) and the peak wavelength for the ultraviolet-excited spectrum of the phosphor is supposed to be lambdaFL(nm). As a result, any deterioration of the phosphor layer 2 which might be caused by short-wave- length ultraviolet rays of high energy can be prevented, thereby improving the characteristic of the lamp.

Abstract: PURPOSE:To acquire the voltage of an average level which is extremely approximate to the center voltage level by providing a voltage control means which controls the frequency detection output voltage in a preamble period of an input signal and in response to a relevant bit pattern. CONSTITUTION:In a reception system of e car telephone, the signal received through an antenna undergoes twice the conversion of frequency and then is supplied to a frequency detector 2 through a limiter amplifier from an input terminal 1 for execution of the detection of frequency. This frequency detection output voltage V1 is connected in series to the resistors 3 and 4. Then the converted signal is supplied to a resistance voltage divider consisting of an ON/OFF switch 5 which is turned on in a due period by a control pulse Vout that rises at the rise of a preamble period and falls right before the start of a unique word period and then multiplied by a (0<a<1). Thus the voltage V1 is controlled in accordance with a bit pattern of the preamble period of an input signal and therefore an average voltage level which is extremely approximate to the center voltage level can be acquired.
