Filed: 1987-11-28
Abstract: PURPOSE:To prevent a deleting from being remained and to improve recording information at a rewriting time by causing the area of a laser spot at a deleting time to be larger than the laser spot at a writing time. CONSTITUTION:At the deleting time, a constant bias voltage from a bias power source generator 17 is subtracted from an output to be based on difference between the output sum of optical sensors 11 and 13 from a differential circuit 15 and the output sum of optical sensors 12 and 14 by a differential circuit 16. Then, this output is obtained as a focus error signal. Thus, when a focus servo circuit is constituted in such a way, a laser light beam 1, whose focus is matched at the writing time, goes to be a laser light 2 to be dislocated only by a distance to correspond to an (a). As the result, a laser spot diameter on an optical recording material surface 3 goes to be large from a diameter d0 at the writing time to a diameter d1.

Abstract: PURPOSE:To supervise its own multiplexing circuit by utilizing an idle time slot so as to insert a supervisory pulse. CONSTITUTION:The first 2-bit of 8 bits of a signal to be multiplexed 101 is used for the insertion of '10'. Two bits being 3rd and 4th bits of 8 bits are used for a multiplexed signal 102 for the insertion of '10'.

Abstract: PURPOSE:To obtain practical and sufficient hue, tone reproducibility and dispersibility of the title toner by subjecting a quinacridone compd. classified into C.I. Pigment Red 122 (73915) and a binding resin to a prescribed treatment. CONSTITUTION:The toner is obtd. by mixing and dispersing 100pts.wt. of the binding resin and 40-400pts.wt. of a colorant composed of the quinacridone compd., followed by crushing the obtd. mixture to obtain crude milled powders having a mean particle size of 10-1,000mum, and then by mixing and dispersing 100pts.wt. of the binding resin having the same or different kind to said binding resin, and 4-20pts.wt. of the crude milled powders, followed by milling and classifying the obtd. mixture to obtain powders having a final mean particle size of 5-25mum. When the final particle size is less than 5mum, the electrostatic charge characteristic of the toner is deteriorated. When the final particle size exceeds 25mum, the mixed color property of the toner is reduced. Thus, the dispersing property of the colorant in the binding resin can be improved, even in case when the colorant having the low dispersibility is incorporated in the binding resin. The toner having the excellent characteristics can be obtd.

Abstract: PURPOSE:To improve durability and corrosion resistance and to permit stable recording of information for a long period of time by incorporating an alloy having a specific compsn. into a recording layer. CONSTITUTION:This medium has a substrate 1 and the recording layer 2. The information is recorded and erased with this medium by projecting a light beam 5 via the substrate 1 to the recording layer 2 to change the optical characteristic in the irradiated part.

Since the alloy having such compsn. has a large difference between the reflectivity in the crystalline material and the reflectivity in the amorphous material, a high signal level is maintained. Further, the alloy having said compsn. has high chemical stability and, therefore, has the high durability and corrosion resistance.
