Title: Time base corrector for recording medium playing device
Inventor: SAKANO TSUTOMU
IPC: H04N5/95
Filed: 1990-02-09
Abstract: PURPOSE:To remote residual jitter by detecting phase difference between a reproducing clock and a reference clock, outputting a phase error signal corresponding to the phase difference, and executing phase control upon the demodulation output of the first demodulating means corresponding to this phase error signal. CONSTITUTION:A phase comparator 36 detects the phase difference between an output dividing the reproducing clock by a frequency divider 34 and an output dividing the oscillation output of a VCXO (voltage controlled crystal oscillator) by a frequency divider 35. The low area component of the phase difference signal generated by this comparator 36 passes through an LPF 37 and becomes the controlled voltage of a VCXO 32. In such a way, when playing a video disk, the read clock of a memory 29 is fixed and the stored information of the memory 29 is read out synchronously with this fixed clock. Further, since the phase control is exerted upon the master clock of a video demodulation system 5 corresponding to the low area component of the phase difference between this fixed clock and the reproducing clock so that an audio output without jitter can be led out, sound quality can be more improved.

IPC: G11B7/253
Filed: 1987-02-13
Abstract: PURPOSE:To increase reproduction contrast and to enhance mass productivity with simple constitution which permits rewriting by forming a recording layer contg. Si and fine metal particles on a substrate which releases a gaseous component when the surface part is heated. CONSTITUTION:The recording layer 2 and a protective layer 3 are laminated on the substrate 1. The surface part of the substrate is formed of an org. material which generates the gaseous component when heated. The recording layer is the film contg. Si and metal particles and absorbs light energy. The recording layer is heated by projection of the light energy thereon and the projected region of the recording layer is floated from the substrate by the gas released from the substrate. Information is recorded by the projecting parts formed in such a manner. The projecting parts are detected by reflected light at the time of reproducing. The light beam of the power lower than the power of the light beam for recording is projected on the recording layer to release either the pressure of the gas or the stress accumulated in the recording layer to erase the projecting parts at the time of erasing. The reproduction contrast is, therefore, enhanced and the mass productivity is improved with the simple constitution which permits rewriting.
