摘要： The present invention relates to a slider (42) 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 (42) to be kept virtually constant over the entire area of a storage medium (5), 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 (5) which is driven at a constant angular velocity, having a slider (42) which is attached by means of a spring arm (41) to a carriage (3) and floats on an air cushion above or under the rotating storage medium (5), and having a guide (1) which guides the carriage (3) relative to the storage medium (5), in which the guide (1) is arranged such that the attachment point of the spring arm (41) to the carriage (3) is guided closer to the surface of the storage medium (5) as the radius of the storage medium (5) increases.
摘要翻译：本发明涉及一种具有恒定飞行高度的滑块（42），其以恒定的角速度运行。本发明的一个目的是提出一种简单且具有成本效益的解决方案，以使滑块（42）的飞行高度在存储介质（5）的整个区域上保持实质上恒定，尽管在以恒定的角速度运行。根据本发明，该目的通过用于以恒定角速度驱动的存储介质（5）的驱动来实现，该驱动器具有滑块（42），该滑块通过弹簧臂（41）连接到滑架 3），并且浮动在旋转存储介质（5）上方或下方的气垫上，并且具有引导滑架（3）相对于存储介质（5）的引导件（1），导向器（1）布置成使得随着存储介质（5）的半径增加，弹簧臂（41）到托架（3）的附接点被更靠近存储介质（5）的表面被引导。
