Abstract
Recording media press systems and methods of operating such press systems. Press system embodiments include a first die and a second die. The press system further includes a mandrel extending along a longitudinal mandrel axis through the first die. A rod portion of the mandrel to receive a magnetic recording disk to be pressed. The press system further includes a foil holder coupled to the first die. The foil holder to clamp a first portion of an embossing foil to the first die and allow the clamped foil portion to move in a radial direction relative to the foil holder.
Claims15
A press system, comprising:
- a first die;
- a second die;
- a mandrel extending along a longitudinal mandrel axis through the first die, a rod portion of the mandrel to receive a magnetic recording disk to be pressed;
- a foil holder coupled to the first die, the foil holder to clamp a first portion of an embossing foil to the first die and allow the clamped foil portion to move in a radial direction relative to the foil holder;
- and
- a second foil holder coupled to the second die, the second foil holder to clamp a portion of a second embossing foil to the second die and to allow the clamped foil portion to move in a radial direction relative to the foil holder.
A press system, comprising:
- means for clamping a portion of an embossing foil to a first die of a die press with a spring tensioned clamp;
- means for receiving a recording media disk in the die press;
- and
- means for pressing the embossing foil against the recording media disk to emboss a side of the recording media disk with a discrete track recording pattern.
