Disk drive with variable density data tracks

A disk drive has multiple disk surfaces and corresponding heads, each disk surface includes multiple regions, and each head is for recording on and playback of information from a corresponding disk surface. The data track density in a first region on a first disk surface is greater than the data tra...

More Information
Summary:A disk drive has multiple disk surfaces and corresponding heads, each disk surface includes multiple regions, and each head is for recording on and playback of information from a corresponding disk surface. The data track density in a first region on a first disk surface is greater than the data track density in a first region on a second disk surface, the data track density in a second region on the first disk surface is less than the data track density in a second region on the second disk surface, the first regions are radially similarly situated regions and the second regions are radially similarly situated regions.
