Abstract
A data storage device includes a track layout having three data sections. A first spin pad having a first length is located between a first and second data section. A second spin pad having a length that is different from the first length is located between the second data section and a third data section. A method for determining the lengths of the spin pads is also provided.
Claims22
A data storage device for storing and accessing data in tracks on a medium, each track having a data layout comprising:
- a first data section;
- a second data section;
- a third data section;
- a first spin pad located between the first data section and the second data section and having a first length;
- and
- a second spin pad located between the second data section and the third data section and having a second length that is different from the first length.
A method of determining the length for a spin pad section in a track layout of a storage medium, the method comprising:
- determining a nominal time period between a detection of a reference mark and a beginning of the spin pad;
- and
- using the nominal time period to set the length for the spin pad.
A data storage medium capable of storing data and having a track layout comprising:
- a first data section and a second data section;
- and
- overwrite protection means in the layout for preventing the first data section from overwriting the second data section based in part on the length of the first data section.
