Abstract
A hard disk drive includes a base deck that is coupled to a cover, a motor assembly that is coupled to the base deck, and magnetic recording media that is coupled to the motor assembly. The motor assembly includes a magnetic bearing with a horizontal magnetic bearing component and a vertical magnetic bearing component.
Claims20
A hard disk drive comprising:
- a base deck coupled to a cover;
- a motor assembly coupled to the base deck;
- and
- magnetic recording media coupled to the motor assembly,
- the motor assembly including a magnetic bearing with a horizontal magnetic bearing component and a vertical magnetic bearing component.
2 more elements
A motor assembly comprising:
- a stationary component coupled to or including a first magnetic pole having a first magnetic polarity;
- and
- a rotatable component coupled to or including a second magnetic pole having a second magnetic polarity that repels the first magnetic polarity, the first magnetic pole and the second magnetic pole are arranged with respect to each other to form a first pair of repelling magnetic poles to create a horizontal magnetic bearing component;
- and
- a second pair of repelling magnetic poles to create a vertical magnetic bearing component.
2 more elements
A base deck for a hard disk drive, the base deck comprising:
- a floor portion and side wall portion;
- and
- a motor assembly coupled to the floor portion and including a stationary component and a rotatable component, the motor assembly including a magnetic bearing having a horizontal magnetic bearing component and a vertical magnetic bearing component, the magnetic bearing arranged such that the rotatable component levitates and does not contact the stationary component.
