Abstract
A data storing medium and a hard disk drive (HDD) having the data storing medium. The data storing medium includes a recording zone where data is recorded and/or reproduced, and a non-recording zone disposed outside the recording zone to overlap with an end of a ramp at which a slider is parked, the non-recording zone including a plurality of micro bumps formed thereon to reduce adsorption between the slider and a surface of the data storing medium. The HDD includes a disk-shaped data storing medium, a slider with a magnetic head to record and/or read data to/from the data storing medium, and a ramp arranged at an outer edge of the data storing medium in which of the slider is parked.
Claims19
A data storing medium, comprising:
- a recording zone where data is recorded and/or reproduced;
- and
- a non-recording zone disposed outside the recording zone to overlap with an end of a ramp at which a slider with a magnetic head is parked, the non-recording zone including a plurality of micro bumps formed thereon to reduce adsorption between the slider and a surface of the data storing medium.
A HDD (hard disk drive) including a disk-shaped data storing medium, a slider with a magnetic head to record and/or read data to/from the data storing medium, and a ramp arranged at an outer edge of the data storing medium on which the slider is parked, the data storing medium comprising:
- a recording zone where data is recorded and/or read by the magnetic head;
- and
- a non-recording zone arranged outside of the recording zone to overlap with an end of the ramp and having a plurality of micro bumps to prevent adsorption between the slider and a surface of the data storing medium.
A hard disk drive, comprising:
- a hard disc including a recording region in which data is recordable and readable, and a non-recording region disposed around the recording region and having a plurality of irregularities formed thereon;
- a slider having a magnetic head associated therewith and being movable along the recording and non-recording regions of the hard disc;
- and
- a ramp on which the slider is parkable when the hard disk drive is powered off and having a slope extending over a surface of the non-recording region.
A method of manufacturing a hard disc usable with a hard disk drive, the method comprising:
- irradiating a laser onto an outer ring of the hard disc to expand a surface of the hard disc such that a plurality of bumps are formed in the outer ring of the hard disc.
