Scissoring load ramp for a removable media disk drive
First Claim
1. A load ramp for use in a disk drive of the type that accepts a removable cartridge containing a storage medium, said disk drive having at least one load beam, said load ramp comprising:
- a base;
at least one arm pivotally attached to said base,said arm having a load beam engaging end, said arm pivoting between a first position, wherein the load beam engaging end of said at least one arm tilts toward the planar surface of the medium forming a ramp for allowing the at least one arm to slide up onto the load ramp, and a second position, wherein the load beam engaging end of said at least one arm tilts away from the surface of the medium allowing the medium to be accepted by said disk drive.

Abstract
An apparatus for loading and unloading heads from a removable cartridge disk drive. The apparatus comprises a scissoring load ramp that has a pair of pivoting arms. Each arm has a ramped end that pivots between and open and a closed position. In the open position, the ramped ends pivot away from each other and away from the surface of the media providing sufficient space for media to fluctuate during insertion and ejection from the drive. In the closed position, the ramped ends move toward each other and the media to provide a mechanism for loading and unloading the heads to and from the media.

8. A load ramp for use in a disk drive of the type that accepts a removable cartridge that stores digital data on a magnetic medium, said disk drive having at least two opposing load beams, said load ramp comprising:
-
a base; two arms pivotally attached to said base, each said arm having a a load beam engaging end, said arms pivoting in opposing directions, such that said arms pivot to a open position wherein the distance between the load beam engaging ends is at a maximum for allowing a medium to be accepted by said disk drive and a closed position wherein the distance between the load beam engaging ends is at a minimum for forming a ramp for disk drive load beams to move up the ramp and off of the surface of the medium. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of moving a read/write head on and off a load ramp and on and off a surface of a removable media, comprising the steps of:
-
a) pivoting an arm having a ramped front surface such that said ramped surface moves upwardly relative to a plane of said media; b) inserting media past the front surface of said arm; c) pivoting said arm such that said ramped surface moves downwardly toward the surface of said of said media; and
,d) moving said head on and off of said load ramp by sliding a load beam attached to said heads over said arm and on and off of said media while said ramped surface is pivoted downwardly. - View Dependent Claims (16, 17)

18. A method of loading media into a disk drive wherein said drive comprises a pair of opposing load beams each having a read/write head disposed on a distal end thereof, said disk drive comprising a load ramp having two arms for maintaining said heads in a parked position off of said media, comprising the steps of:
-
a) pivoting said arms such that a front portion of each arm pivots away from each other and away from a plane of said media; b) inserting media past the front surface of each said arm; c) after said media is inserted into said drive, pivoting each arm such that said front surfaces move toward the surface of said of said media and toward each other. - View Dependent Claims (19, 20)
