Multi-head data storage device with plural data channels per head
A plurality of read/write heads is disclosed for a magnetic media storage system, such as, for example a magnetic tape drive. Each head can include a plurality of data channels. In addition to enhancing data throughput, the plurality of read/write heads can be aligned to read or write bands of tracks on a magnetic tape with only one positioning mode (e.g., without coarse position actuation and control), and also obtain optimum yield and crosstalk values.
1. A data storage system, comprising:
a plurality of read/write heads, each read/write head of said plurality of read/write heads having a plurality of read/write elements;
a plurality of data channels, a subset of said plurality of data channels coupled to a read/write head of said plurality of read/write heads; and
a storage medium, said storage medium including a plurality of storage bands, wherein each read/write head is uniquely associated with a single storage band such that the read/write heads are alignable with a single mode of operation, and each read/write element is associated with a corresponding one of said plurality of data channels and operable to read and write data from or to corresponding tracks of a corresponding storage band;
wherein said plurality of read/write heads comprises at least one read/write head having a read/write element configured for read after write operation as the storage medium travels in a first direction and at least one read/write head having a write/read element configured for read after write operation as the storage medium travels in a second direction opposite the first direction.
2. A data storage system comprising:
a plurality of read/write heads each associated with a corresponding one of a plurality of storage bands extending across a magnetic storage medium wherein each of the plurality of read/write heads is displaced along a direction of travel of the magnetic storage medium relative to an adjacent read/write head and wherein each of the plurality of read/write heads is coupled to at least one of a plurality of data channels;
wherein at least one of the plurality of read/write heads comprises a read/write element configured for read after write operation as the magnetic storage medium travels in a first direction and at least one of the plurality of read/write heads comprises a write/read element configured for read after write operation as the magnetic storage medium travels in a direction opposite the first direction.
