DISC DRIVE, CAPABLE OF ENSURING AN ENCODER A CERTAIN DISTANCE FROM A DISC BY EASILY CHANGING THE HEIGHT OF AN ENCODER HOLDER

摘要

PURPOSE: A disc drive is provided to install an encoder at a base plate with a narrow area by installing the encoder to be spaced at a certain distance from a disc by changing the height of an encoder holder.;CONSTITUTION: A disc drive is composed of a spindle motor(2), an encoder(30), an encoder holder(20), and a base plate(10). The spindle motor rotates the disc(1). The encoder senses the rotation speed of the disc. The encoder holder fixes the encoder. The base plate includes a holder groove. The encoder holder is inserted into the holder groove. The holder groove is formed by passing through the base plate. The base plate supports the spindle motor.;COPYRIGHT KIPO 2010
