Abstract
A ramp 200 has an attaching portion 221 and an arm holding portion 222. The attaching portion is molded with high polymer material so that the attaching portion has a screw hole 25 for fixing the ramp to the housing of an information recording disk apparatus by a screw. The arm holding portion is molded with high polymer material whose fiction coefficient is small, and the arm holding portion has a storing portion 27 to hold the suspension arm retracted from the recording disk and also has a guide portion 28 against which the suspension arm slides so that it is easily moved in and out of the storing portion 27. The attaching portion 221 and the arm holding portion 222 are united in one by subsequently molding the attaching portion and the arm holding portion.

A ramp for an information recording disk apparatus having a suspension arm to hold a magnetic head for writing to or reading information from a recording disk, and for retracting the suspension arm from the recording disk and holding the suspension arm, the ramp comprising:
- a plurality of blocks each having a connecting surface, each block being formed from a different high polymer material;
- a locking unit formed in each of the connecting surfaces;
- and wherein each of the blocks comprises:
- an attaching portion formed from high polymer material, wherein each attaching portion has a screw hole for fixing the ramp to a housing of the information recording disk apparatus with a screw;
- and
- an arm holding portion formed from high polymer material having a small coefficient of friction, the arm holding portion having a storing portion to hold the suspension arm retracted from the recording disk, and also having a guide portion against which the suspension arm slides for facilitating movement of the suspension arm in and out of the storing portion.
