Abstract

Disk, which is the main parts of hard disk drive product, is packed in the box which will be called Disk Caddy and it will used to supply the hard disk drive manufacturing. The disk caddy will be open/close to take out the disk for production, but some contamination problem is happening with this opening/closing. The locking structure usually makes some particle. So the invention was born to prevent this contamination problem. We made shield at the edge of caddy not to make the particle which made by caddy opening/closing to the disk. Some example picture will be attached here Picture 1. Disk Caddy

  The shield to prevent disk surface pollution with particle induced by open/close of disk cassette

Disk, which is the main parts of hard disk drive product, is packed in the box which will be called Disk Caddy
and it will used to supply the hard disk drive manufacturing. The disk caddy will be open/close to take out the disk for production, but some contamination problem is happening with this opening/closing. The locking structure usually makes some particle. So the invention was born to prevent this contamination problem.

We made shield at the edge of caddy not to make the particle which made by caddy opening/closing to the disk. Some example picture will be attached here

The shield will cut the way of particle from the lock area to the disk stoking area, perfectly so no particle will go to the disk from locking area to disk stocking area. The shield itself can made separately or made in a unit body with lid ( or Top Cover ) or caddy main body ( or cassette ) . But we made most easy one here.
