Abstract
In an implementation, a media drive comprises bit patterned magnetic media and one or more modules. The one or more modules are to cause data to be written on the bit patterned magnetic media in a data sector that includes a synchronization mark disposed between data blocks of the data sector.
Claims21
A media drive comprising:
- bit patterned magnetic media;
- and
- one or more modules to cause data to be written on the bit patterned magnetic media in a data sector, including causing synchronization marks to be written between data blocks of the data sector, the synchronization marks configured such that a bit insertion or a bit omission in one of the data blocks in the data sector does not affect another of the data blocks in the data sector.
A media drive comprising:
- bit patterned magnetic media configured to maintain a data sector that includes synchronization marks disposed between data blocks of the data sector;
- and
- one or more modules configured to cause data to be written in the data sector, including causing the synchronization marks to be written between the data blocks of the data sector, the synchronization marks configured such that a bit insertion or a bit omission in a first one of the data blocks in the data sector does not affect a second one of the data blocks in the data sector, and to read the data from the data blocks of the data sector.
A method comprising:
- writing a data sector on bit patterned magnetic media by:
- causing a first data block to be written to the bit patterned magnetic media for the data sector;
- causing a synchronization mark to be written to the bit patterned magnetic media after the first data block;
- and
- causing a second data block to be written to the bit patterned magnetic media after the synchronization mark for the data sector, the synchronization mark configured such that a bit insertion or a bit omission in the second data block does not affect the first data block.
