Title: Method for controlling optical recording
Inventor: ICHII HIROSHI
IPC: G11B7/125
Filed: 1982-07-28
Abstract: PURPOSE:To provide a large margin to the environmental variation such as temperature and power voltage by setting up the quantity of irradiated light of a recording beam in a saturated range for the change of jitter variable, and to form appropriate recording pits having no jitter on the whole positions of a disc. CONSTITUTION:Digital data ( I ) to be recorded are inputted to an MFM modulating circuit 1 and converted into an MFM signal (II). In a jitter compensating circuit 2, an AND gate 4 finds AND between an MFM signal outputted from the MFM modulating circuit 1 and a signal delayed by DELTAT by a DELTAT delay circuit 3 to generate a jitter compensated MFM signal (III) of which pulse width is compressed by DELTAT. The jitter compensated MFM signal is converted into a power pulse signal by a light source driving circuit 5 and then supplied to a laser light source 6. The laser light source 6 forms pits on a disc medium with the jitter-compensated pulse width.

Filed: 1992-04-24
Abstract: PURPOSE:To provide a recorder whose print quality is always excellent in which deterioration of a thermal head hardly takes place by aborting a part exposed to an environmental condition at least at a tip of recording paper when it is discriminated that the recording paper is not suitable for recording due to its secular change. CONSTITUTION:When a reception or copy command is not implemented, a CPU 9 reads a current time from an RTC device 18 at a prescribed time interval and subtracts a time stored in a setting time data memory 22 from the read time data to calculate the elapsed time. When the time is, e.g. 3 months, it is discriminated that the recording paper is not suitable for recording and a recording paper driver 16 is driven for a prescribed time, the tip of the recording paper exposed to environment is discharged, the part is cut off by a recording paper cutter 17, its cut number of times is counted up and stored in a memory. When the number of times of cutting is, e.g. 4 or over, since it means the recording paper is subjected to environment for one year or over, it is discriminated that the entire recording paper is not suitable for recording and a message urging replacement of the recording paper is displayed on an operation panel 3.
