Abstract
A device and method for preparing media discs (2) in which servowriting and verification of the media may be carried out simultaneously. A common monolithic platform (1) is provided which supports air bearing systems which allow movement of a media disc rotary carrier (5), a servowriting headstack (3) and certifier headstack (4). Indirect drive may be provided to the rotary carrier (5) via coupling means (62).
Claims18
A device for preparation of a media storage disc comprising a single monolithic support platform, a rotary carrier arranged for rotation of a media disc supported on said platform, a write head arranged for substantially radial movement relative to said carrier and for servo writing of data to said media disc and a certifier head arranged for substantially radial movement relative to said carrier and for verification of the media disc.
A method of preparing media storage discs comprising the steps of mounting a media disc on a rotary carrier supported on a platform, verifying the integrity of the mounted media disc using a certifier head and servowriting data to the mounted media disc with a write head without removing the media disc from the rotary carrier between the verifying and servowriting steps.
A device for preparation of a media storage disc comprising a single monolithic support platform, a rotary carrier arranged for rotation of a media disc supported on said platform, a write head arranged for substantially radial movement relative to said carrier and for servo writing of data to said media disc, a certifier head arranged for substantially radial movement relative to said carrier and for confirming the integrity of the medium of the disc, and indirect drive means for driving the rotary carrier, the drive means comprising a motor mounted independently of the rotary carrier, and coupling means for transmitting the drive to the rotary carrier whilst minimizing the transmission of any undesirable vibration.
A device for preparation of a media storage disc comprising:
- a single monolithic support platform, a rotary carrier supported on said platform and arranged for rotation of a media disc on an air bearing system, the carrier being driven by a motor mounted independently of the rotary carrier and arranged to drive the carrier via a resilient coupling;
- a write head arranged for substantially radial movement relative to said carrier and for servowriting of data to said media disc, the write head being carried on an air bearing system;
- and
- a certifier head arranged for substantially radial movement relative to said carrier and for confirming the integrity of the medium of the disc.
A device for preparation of a media storage disc comprising:
- a single monolithic support platform, a rotary carrier supported on said platform and arranged for rotation of a media disc on an air bearing system, the carrier being driven by a motor mounted independently of the rotary carrier and arranged to drive the carrier via a drive belt;
- a write head arranged for substantially radial movement relative to said carrier and for servowriting of data to said media disc, the write head being carried on an air bearing system;
- and
- a certifier head arranged for substantially radial movement relative to said carrier and for confirming the integrity of the medium of the disc.
