Abstract
Minimizing slider vibration effects on a magnetic transducer coupled to a slider are described herein. In one embodiment, a method is described for minimizing slider vibration effects on a magnetic transducer coupled to the slider. A mass component of the slider is adjusted such that at least one pitch nodal line and/or at least one roll nodal line of the slider approximately coincide with an intersection point, and the magnetic transducer is positioned to approximately coincide with the intersection point.
Claims25
A method of minimizing slider vibration effects on a magnetic transducer coupled with said slider, said method comprising:
- adjusting a mass component of said slider such that at least two nodal lines of said slider approximately coincide with an intersection point;
- and
- positioning said magnetic transducer to approximately coincide with said intersection point.
A slider for a hard disk drive, said slider comprising:
- a slider body configured, such that at least two nodal lines of said slider approximately coincide with an intersection point;
- and
- a magnetic transducer is approximately coincident with said intersection point.
A hard disk drive comprising:
- a base casting for providing coupling points for components and sub-assemblies of said hard disk drive;
- a motor-hub assembly to which at least one disk is coupled allowing rotation of said disk about an axis approximately perpendicular and centered to said disk, wherein said motor-hub assembly is coupled to said base casting, wherein said disk comprises at least one surface of data tracks;
- and
- a slider coupled to said base casting by means of a suspension and an actuator such that said slider is arcuately moved across said data tracks, said slider comprising:
- a slider body configured, such that at least two nodal lines of said slider approximately coincide with an intersection point;
- and
- a magnetic transducer for conveying data to and from said data tracks, said magnetic transducer coupled approximately coincident with said intersection point.
