Abstract
In an apparatus wherein a recording medium is conveyed by a conveying system with the front surface of the recording medium opposed to recording heads and information is recorded on the recording medium by liquid droplet jet, a first speed meter is provided on the back side of the recording medium and further, a second speed meter for detecting liquid droplet jet speed together with the first speed meter is provided at a predetermined location, whereby the recording position is adjusted. The first and second speed meters may preferably be optical Doppler velocimeters which will not cause any speed detection error with fluctuation of the wavelength of a light source.
