Abstract
A data storage method, apparatus and system that increase drive capacity, minimize latency, reduce write access time and improve drive lifetime is described in this invention. In one embodiment, the data storage device described here is a composite hard disk drive comprises a number of recording media platters labeled from 1 to n, where n is greater than or equal to 2; wherein there exist two positive integer n1 and n2, where n1 and n2 are between 1 and n; n1 is not equals to n2; wherein the data tracks for the media platters n1 and n2 are written based on one of the following: 1) different RTs; 2) different WAs; or 3) different RTs and different WAs.

A composite hard disk drive, comprising:
- a number of recording media platters labeled from 1 to n, wherein:
- n is greater than or equal to 3;
- there is an integer n1 between 1 and n;
- n1 is less than n/2;
- the recording media platter labeled from 1 to n1 are written using a first recording technology (RT);
- all other recording media platters of the number of recording media platters are written using a second RT that is different from the first RT.
A composite hard disk drive, comprising:
- a number of recording media platters labeled from 1 to n, wherein:
- n is greater than or equal to 3;
- there is an integer n1 between 1 and n, wherein:
- n1 is less than n/2;
- the recording media platter labeled from 1 to n1 are written using a first write architecture (WA);
- all other recording media platters of the number of recording media platters are written using a second WA that is different from the first WA;
- and
- the recording head and recording media surface corresponding to the first WA and the second WA has a design, material, structure, number of sensors and transducer integrated or critical specification to be different.
