Doesn't really say that much, "fewer than the competition", when the competition doesn't have any terabyte drives yet.

There are only so many platter manufacturers. What Michael is emphasizing is that the platter guys they are using will have higher density platters available to Seagate before Western Digital.

Kris is correct here. It is also important to note that platter manufacturers generally operate under license from the hard drive manufacturer. Thus, the plattr manufacturer generally gets to use the proprietary technology of the hard drive manufacturer. This means that the platters in Seagate's perpendicular drives will be made with their technology, whereas the platters of a competing hard drive manufacturer, e.g., Western Digital, will be made with a different technology.

Accordingly, the platters made by under different licenses for different companies will differ in many respects, including platter size, platter weight, magnetic layer thickness, microwaviness (actual term), surface roughness, theoretical/actual capacity etc. All these things go to cost of manufacture.
