Abstract
A method for synchronizing writing to a bit patterned media includes: reading bits from skipped blocks on the bit patterned media, using timing of bits read from the skipped blocks to update a write clock, and writing request data to physical blocks on the bit patterned media, interleaved with the skipped blocks. An apparatus that operates in accordance with the method is also provided.
Claims14
A method for synchronizing writing to a bit patterned media, the method comprising:
- reading bits from skipped blocks on the bit patterned media;
- using timing of bits read from the skipped blocks to update a write clock;
- and
- writing request data to physical blocks on the bit patterned media, interleaved with the skipped blocks.
1 more element
An apparatus comprising:
- a bit patterned storage media;
- a recording head for reading bits from the storage media and writing data to the storage media, wherein the recording head reads bits from skipped blocks on the storage media;
- and
- a controller including a write clock, wherein timing of the bits read from the skipped blocks is used to update a write clock, and the recording head writes request data to physical blocks on the storage media, interleaved with the skipped blocks.
