Title (EN) COLLISION PREVENTION METHOD AND APPARATUS BETWEEN RECORDING MEDIUM AND LENS
(FR) PROCÉDÉ ET DISPOSITIF DE PRÉVENTION DE COLLISION ENTRE UN SUPPORT D'ENREGISTREMENT ET UNE LENTILLE
Abstract: front page image
(EN)A method and apparatus for preventing a collision between a recording medium and a lens are disclosed. The method for preventing the collision between the recording medium and the lens includes controlling a gap error signal (GES) between the recording medium and the lens to be maintained at a near field level, detecting a collision between the recording medium and the lens, pulling out the lens from the recording medium during a predetermined time so as to prevent a re-collision between the recording medium and the lens, and re-controlling the gap error signal (GES) between the recording medium and the lens to be re-maintained at the near field level.
(FR)L’invention concerne un procédé et un dispositif pour empêcher une collision entre un support d'enregistrement et une lentille. Le procédé pour empêcher la collision entre le support d'enregistrement et la lentille consiste à commander un signal d'erreur d'espace (GES) entre le support d'enregistrement et la lentille pour qu'il soit maintenu à un niveau de champ proche, détecter une collision entre le support d'enregistrement et la lentille, écarter la lentille du support d'enregistrement pendant un temps prédéterminé de manière à empêcher une nouvelle collision entre le support d'enregistrement et la lentille, et commander de nouveau le signal d'erreur d'espace (GES) entre le support d'enregistrement et la lentille pour qu'il soit maintenu de nouveau au niveau de champ proche.
