    摘要： A method is provided for manufacturing a synthetic silica glass. The method includes the steps of maintaining a silica glass member, which is formed using a flame hydrolysis method and having an OH group concentration of about 500 ppm to about 1300 ppm, at a predetermined holding temperature for a predetermined period of time so as to substantially relax the structure of the silica glass member. The method further includes the step of subsequently cooling the silica glass member to a first predetermined temperature at a cooling rate of about 10 K/hour or less, and thereafter, cooling the silica glass member to a second predetermined temperature at a cooling rate of about 1 K/hour or less. The method further includes the step of further cooling the silica glass member to a third predetermined temperature at a cooling rate of about 10 K/hour or less.

    摘要： A sync clock signal for information reproduction is generated using a binary signal obtained from a recording medium as a reference signal. The phase of the binary signal is compared with that of the sync clock signal. A frequency is changed based on the comparison result to generate (2m+1) multi-phase clock signals mutually shifted in phase by an integral multiple of 2&pgr;/(2m+1). Any one of these clock signals is used as the sync clock signal for information reproduction. The binary signal is delayed by a controllable delay time to generate a binary delayed signal, the phase of which is compared with those of the clock signals. The delay time of the binary delayed signal is controlled based on the comparison result so that the level change timing of the binary delayed signal is moved on a time base away from that of the sync clock signal.
