摘要： A frequency demodulating circuit, optical disk and preformatting device having a decoder for decoding a bit “0” and a bit “1” for reproducing address information recorded as a wobble groove. The decoder determines whether an output is a digital “1” or a digital “0” so that even if the waveform of the reproduced signal is erratic or unstable due to a defect, a digital “1” or a digital “0” can be correctly identified by utilizing window pulses. Changes in the slop of a zero cross point of the groove wobble are prevented from occurring by making the groove wobble amplitude fluctuate according to the signal frequency modulation which also greatly reduces jitter and allowing satisfactory acquisition of the address information. Oversampling clock signals of biphase bits are generated by frequency division of data clock signals. Since demodulation is accomplished with a single phase lock loop circuit in the data system using clock signals for both the data and the addresses, the configuration can be made extremely simple. By means of polarity of the playback signal mark having phase information, it is determined whether the beam that scans the optical disk is above the land or above the groove. The marks containing phase information are formed on the base disk surface solely by the on and off control of the paired cutting beams with respect to the direction of the time axis, for easy preformatting of a mark to permit acquiring (phase) position information with high precision.

摘要： A slit pipe which is compressible in a radial direction thereof is attached to a watch case between a pair of leg portions. A groove is formed in a link of a watch band so as to be engaged with the slit pipe. The groove has an opening formed on the underside of the link, an introducing portion communicating with the opening, a groove portion formed at an innermost end of the groove. The opening has a width smaller than an outer diameter of the pipe, and larger than an outer diameter of the pipe when compressed. The groove portion has an inner diameter larger than the outer diameter of the pipe. Thus, the pipe may be inserted in the groove portion from the opening passing through the introducing portion.

In a first method, in a recordable and reproduceable area, a twin-track structure of lands/grooves is configured such that tracks on which lands become recording tracks and tracks on which grooves become recording tracks form a double spiral. In a read-only area, pits are arrayed such that tracks in the radial direction of the disk are formed in a data area. In a second method, in a recordable and reproduceable area, a land/groove-alternate track structure is configured such that grooves become data recording tracks in the circular track next to the circular track in which lands become data recording tracks, and lands become data recording tracks in the next circular track. In the read-only area, pits are arrayed such that tracks in the radial direction of the disk are formed in the data area.
