Title: Optical recording medium
Inventor: UENO OSAMU
IPC: G11B7/24079
Filed: 1988-02-08
Abstract: PURPOSE:To obtain a recording medium which has a high track density and C/N and decreased medium noises by providing tracks formed of recording layers via intervals on a substrate and setting the width size thereof at about the width equal to the half-amplitude level of a light spot or below. CONSTITUTION:The tracks 4 consisting of the recording layers 3 are formed on the substrate 2 and the width T thereof is set at the half-amplitude level OMEGA2 of the semiconductor laser spot for recording or below. The laser is projected to the prescribed sections of the layer 3 to form recording dots 6 of the width OMEGA2 or below. The width B of the dots 6 is, therefore, the same as the width T of the tracks 4 and since this width is smaller than the width OMEGA2, the track pitch TP can be set smaller and the track density is increased. Since the dots 6 can be formed nearly to a rectangular shape, the waveform distortions at time of reproduction are eliminated and the C/N and jitter are improved; in addition, the layers 3 are not formed except in the tracks 4 and, therefore, the medium noises are decreased. The high-quality medium is thereby obtd.

Abstract: PURPOSE: To provide a small printer which is capable of treating waste liquid without using a waste liquid absorbing body, and forming high-quality images. CONSTITUTION: Cap units 14, 2 of the recovery system units 13, 17 of a head 2 which discharges ink or a processing liquid which makes the ink fixative or more viscous, when a carriage 3 is in the home position, join with their respective discharge heads 2 which discharge the ink and the processing liquid, cap them, and prevent the ink and the processing liquid from evaporating, becoming more viscous and fixative, thereby causing poor discharge. Ink and the process liquid in the head which are absorbed by absorption recovery treatment is stored in a waste liquid reservoir 16 through tubes 15, 3 from a pump unit. The process liquid discharged from the head by recovery treatment is transported to the waste liquid reservoir 16 with a sloped bottom through the tube 3, mixed, made fixative or viscous and stored.
