Title: Optical output set controller
Inventor: OGAWA HIROSHI
IPC: G11B7/125
Filed: 1988-11-29
Abstract: PURPOSE:To reduce an error generation rate and to attain the optical recording of high reliability by controlling a light source to a condition that the reflected light of prescribed light quantity is detected when a prescribed time needed for the formation of a recording pit to an optical recording medium elapses from the output timing of an optical pulse by the light source. CONSTITUTION:A driving control means 14 of the light source for data writing to an optical recording medium 1 executes data writing to the optical recording medium 1 by the optical pulse while gradually increasing the optical output of the light source. Based on the detecting output of an optical detecting means to detect the light quantity of the reflected light by the optical recording medium 1 for the light outputted from the light source, the optical output of the light source is automatically controlled to the optimum condition at real time so that the reflected light by the optical recording medium 1 can be the prescribed light quantity when the prescribed time needed for the formation of the recording pit to the optical recording medium 1 by the optical pulse elapses after the output timing of the optical pulse by the light source. Thus, when data are written to the optical recording medium 1, the error generation rate is kept low and the optical recording of high reliability can be executed.

Title: Ink jet recording method
Inventor: MATSUBARA MIYUKI
IPC: H04N1/12
Filed: 1992-11-12
Abstract: PURPOSE:To record a high quality image having no streak even on a recording medium having a elatively high ink absorbing power. CONSTITUTION:Main scanning is performed by moving a recording head arranged with a plurality of rows of ink delivery elements in a direction different from the arranging direction of the ink delivery elements. After finishing the main scanning, image recording is performed by carrying a recording member by a specific width in a direction different from main scanning direction. In this regard, recording region of the recording head is split into a plurality(n) of subregions which are then used for performing main scanning (n) times for a unit image region on the recording medium. Images decimated at a printing ratio of l/n are then recorded sequentially thus completing recording of a unit image region. Printing ratio for pixel group at a border part is set lower than that for the entire unit image region at least once among (n) times of main scanning, thus increasing the number of pixels to be recorded at the border part through single main scanning.
