ABSTRACT:
The present invention relates to a slider having a constant flying height for an optical drive which is operated at a constant angular velocity. It is an object of the invention to propose a simple and cost-effective solution to allow the flying height of the slider to be kept virtually constant over the entire area of a storage medium, despite a variable linear velocity during operation at a constant angular velocity. According to the invention, this object is achieved by a drive for a storage medium which is driven at a constant angular velocity, having a slider which is attached by means of a spring arm to a carriage and floats on an air cushion above or under the rotating storage medium, and having a guide which guides the carriage relative to the storage medium, in which the guide is arranged such that the attachment point of the spring arm to the carriage is guided closer to the surface of the storage medium as the radius of the storage medium increases.
