Title: Disk pit shape control method and disk recording device
Inventor: AZUMA RYOJI
IPC: G11B7/26
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To provide an optimal pit shape by controlling the on/off timing of a modulated digital signal to be recorded. SOLUTION: Digital data to be recorded is modulated for adding an error correction code by a digital signal converter 6 and then a digital signal is controlled by a duty factor controller (DC) 8. A signal outputted from the DC 8 is used to actuate an optical modulator 3 by an optical modulator driving circuit 7 according to the controlled digital signal and a laser beam is turned on/off. The DC 8 is composed of an H side pulse reducing circuit and an H side pulse expanding circuit, the reducing circuit being for reducing a signal level H side pulse and the expanding circuit being for expanding the same to an optional pulse width by a select switch. Thus, a basic digital signal, in this case an EFM modulated digital signal, is freely controlled within a select range by the DC 8. Thus, the number of control parameters is increased for stamper manufacturing in a disk manufacturing process and optimal pit formation of a disk is facilitated.

Filed: 1987-11-20
Abstract: PURPOSE:To detect not only whether or not there is a foreign matter, but also the size of the foreign matter by estimating the size of the foreign matter from the level of a shock sound. CONSTITUTION:When an AC high voltage is applied between a center conductor 2 and a container 1 of a gas-insulation shield device, the foreign matter 3 enters motion between the center conductor 2 and the container 1 with a Coulomb force and when the foreign matter 3 strikes on the container 1, the shock sound is transmitted to an ultrasonic wave sensor 4 through the container 1. A detector 7 detects an output signal generated by removing frequency components which are not required for monitoring from the shock sound through a band-pass filter. A foreign matter size decision device 8 incorporates a peak holding circuit and holds the peak value of the output signal of the detector at constant intervals of time. A foreign matter decision device finds the size of the foreign matter from the peak value of the shock sound at each time from the straight line relation on the graph of both the maximum value of the shock sound and the size of the foreign matter, and varies and records the display at constant intervals of time.
