Various methods and apparatus for simultaneously processing two single-sided hard memory disks is provided. Disks are positioned in pairs, with one surface of one disk positioned adjacent one surface of the second disk, with the disk surfaces touching or with a slight separation between them. In this back-to-back orientation, the disk pairs may be processed using conventional double-sided disk processing equipment and techniques. However, each disk will not have two active surfaces. Because of the positioning of the disks during processing, only one surface of each disk will be subjected to full processing. Therefore, each disk will only have one active side.

What is claimed is: 1. A method of manufacturing single-sided hard memory disks, comprising: a. positioning a plurality of disks in pairs, with each pair in a gap merge orientation; b. transferring a pair of gap merge oriented disks to a processing station one pair at a time; c. simultaneously proc
What is claimed is: 1. A method of manufacturing single-sided hard memory disks, comprising: a. positioning a plurality of disks in pairs, with each pair in a gap merge orientation; b. transferring a pair of gap merge oriented disks to a processing station one pair at a time; c. simultaneously processing both disks of the disk pair. 2. The method of claim 1, wherein positioning a plurality of disks in pairs, with each pair in gap merge orientation, comprises positioning the plurality of disks in a disk carrier in gap merge orientation. 3. The method of claim 1, wherein said simultaneously processing both disks of the disk pair comprises texturing. 4. A method of manufacturing hard memory disk having only one active side, comprising: a. combining individual disks into pairs of disks; b. simultaneously processing the pairs of disks one pair at a time. 5. The method of claim 4, further comprising simultaneously processing each pair of disks separate from each other pair of disks. 6. The method of claim 4, wherein simultaneously processing the pairs of disks comprises one or more of texturing, washing, sputtering, burnishing and testing. 7. The method of claim 4, further comprising separating each pair of processed disks following simultaneous processing of the pairs of disks. 8. A method of manufacturing single-sided hard memory disks, comprising: a. providing a plurality of disks; b. positioning the plurality of disks in pairs in a gap merge orientation in a container; c. individually removing the pairs of disks from the container one pair at a time; d. simultaneously processing each pair of disks one pair at a time; e. returning each pair of disks to a container. 9. The method of claim 8, wherein simultaneous processing each pair of disks comprises one or more of texturing, scrubbing, sputtering, burnishing and testing. 10. The method of claim 9, further comprising positioning each disk pair in a contact merge orientation for processing. 11. The method of claim 10, further comprising demerging each pair of disks following texturing and/or scrubbing. 12. The method of claim 8, wherein simultaneously processing each pair of disks comprises texturing and further comprising positioning the disks of each pair in a contact merge orientation for texturing. 13. The method of claim 12, further comprising demerging each pair of disks following texturing. 14. The method of claim 13, wherein demerging each pair of disks comprises positioning the disks in a gap merge orientation. 15. The method of claim 13, further comprising subjecting each disk pair to additional simultaneous processing following demerging. 16. A method of manufacturing hard memory disks having a single active side on each side, comprising: a. providing a plurality of disks; b. changing the orientation of the disks; c. processing the disks two at a time such that only one surface of each disk is subjected to flail processing. 17. The method of claim 16, wherein processing the disks comprises one or more of data zone texturing, laser zone texturing, scrubbing, sputtering, burnishing, testing and servo-track writing. 18. The method of claim 17, further comprising changing the orientation of the disks following one or more of the processes. 19. The method of claim 16, wherein changing the orientation of the disks occurs following processing. 20. A method of manufacturing single-sided hard memory disks having an outer perimeter edge and a center aperture defining an inside perimeter edge comprising: a. providing a plurality of disks; b. placing the plurality of disks in a container, in pairs, with the disks in a contact merge orientation; c. removing the pairs of disks from the container one pair at a time; d. simultaneously burnishing the outwardly facing surface of each disk in a pair; e. positioning the pairs in a container. 21. The method of claim 20, wherein removing the pairs of disks from the container one at a time comprises engaging the disk pairs at their lower outer perimeter edge. 22. The method of claim 21, further comprising engaging each pair of disks at their inside perimeter edge prior to burnishing. 23. The method of claim 21, further comprising moving each disk pair to a different location following removing each disk pair from the container and prior to burnishing. 24. The method of claim 23, further comprising maintaining each disk pair in a contact merge orientation while moving each disk pair to a different location. 25. The method of claim 20, further comprising simultaneously testing the outwardly facing surface of each disk in a pair. 26. The method of claim 25, wherein the testing occurs following burnishing. 27. The method of claim 26, wherein the testing occurs following step e, positioning the disk pairs in a container. 28. The method of claim 27, wherein positioning the disk pairs in a container following burnishing comprises positioning the disk pairs in a contact merge orientation. 29. The method of claim 27, further comprising positioning disk pairs in a container following testing. 30. The method of claim 29, further comprising demerging the disk pairs following testing. 31. The method of claim 30, further comprising separating the demerged disk pairs and positioning the individual disks in containers with the active side of each disk in a container having the same orientation in the container. 32. The method of claim 27, further comprising separating disks based upon results of testing. 33. A method of manufacturing single-sided hard memory disks, comprising: a. providing a plurality of disks; b. merging the plurality of disks into pairs of disks; c c. subjecting each pair of disks to a sputtering process wherein the outwardly facing surface of each disk in each pair is simultaneously sputtered; d. subjecting each pair of disks to a burnishing process wherein the outwardly facing surface of each disk is simultaneously burnished; e. subjecting the pair of disks to a testing process wherein the outwardly facing surface of each disk is simultaneously tested; f. placing the disks in a container. 34. The method of claim 33, further comprising maintaining the orientation of the disk pairs for each of the sputtering, burnishing and testing processes. 35. The method of claim 34, wherein the disk pairs are positioned in a gap merge orientation. 36. The method of claim 34, wherein the disk pairs are positioned in a contact merge orientation.
