Filed: 1989-11-17
Abstract: PURPOSE:To prevent unwanted matter included in magnetic fluid to be attached on a magnetic drum and to improve recording quality by circulating the magnetic fluid, and filtering the unwanted matter included in circulating magnetic fluid. CONSTITUTION:The magnetic fluid 21 is always circulated with a circulation means 25. The unwanted matter included in the magnetic fluid is filtered with a filtering means 26 while being circulated. Therefore, the magnetic fluid 21 can be always kept at a cleaned state. Also, the flow rate of the magnetic fluid 21 in circulating is detected with a flow rate detector 27. A detection circuit 28 detects the viscosity of the magnetic fluid 21 based on the flow rate per unit time detected at the flow rate detector 27. A control circuit 29 controls the opening/closing state of a control valve 30 based on information from the detection circuit 28. As a result, solvent 23 in a housing container 24 flows out via the control valve 30, and the viscosity of the magnetic fluid 21 can be kept constant.

Title: Recording and reproducing method for optical recording disk
Inventor: SHINKAI MASAHIRO
IPC: G11B19/02
Filed: 1991-10-19
Abstract: PURPOSE:To reduce the thermal degeneration between adjacent bits to improve the resolution by making the linear speed for recording higher than that for reproducing to record data and shortening the irradiation time to obtain the reproduced output of the same level. CONSTITUTION:The linear speed for recording is made higher than that for reproducing to record data. In this case, the suitable linear speed for recording is 13 to 10.0m/s.
