摘要： A tray of an optical disk player including a disk mounting portion on which an optical disk is stably mounted; a front wall formed on the front to surround the disk mounting portion; a rear wall formed on the rear of the tray to surround the disk mounting portion, the front wall is formed to have a distance from the center of a spindle to the front wall not less than a value obtained by adding 2.75 mm to a radius of a large-sized disk and not greater than a distance from the center of the spindle to a tray front end. In the tray, by increasing a flutter occurrence speed, although the optical disk player has a high recording/reproducing speed, occurrence of flutter can be prevented, and accordingly it is possible to reduce error in disk reproducing/recording and prevent noise occurrence and wrong operation.
