    Abstract: During self-servowriting, burst information is written within slots defined on tracks of a recording medium. In writing the burst information, write to read interference, caused by large offsets in separate read and write elements of a recording transducer, is to be avoided. In order to avoid the write to read interference, the slots are carefully chosen. The choice of a particular slot can be independent of any predefined order, such as a successive order. Further, the order in which slots are chosen may be altered during the propagation process.

    Abstract: A hard disk unit includes a disk, a controller microprocessor, a host bus interface, a buffer memory, a buffer memory controller, and a disk formatter. The bus interface receives write operations, and the buffer memory controller stores the corresponding write operation data in the buffer memory in the relative order in which the operations are received. The buffer memory controller subsequently transfers the data of a write operation from the buffer memory to the disk formatter, which formats the data and writes it to the disk. The buffer memory controller controls read and write access to the buffer memory. The buffer memory controller includes a set of address registers and a set of block count registers. The microprocessor loads the address registers with the addresses within the buffer memory of the data of two or more write operations. The microprocessor loads the block count registers with the size, in blocks, of the corresponding operations. The microprocessor then issues a single command to the buffer memory controller to transfer the data identified by the address registers and block count registers from the buffer memory to the disk formatter. The address registers and block count registers enable the buffer memory controller to transfer the data of several write operations in any order. Previous buffer controllers are typically capable of transferring the data of several write operations only in the same order in which the data is stored in the buffer memory.

    Abstract: Track positioning of a scanning tape head in a helical tape system may be adversely affected by relative offsets between elements in read element pairs and in write element pairs accessing synchronization patterns. Compensating for variations in the position of read and write elements accessing a given pair of data channels is accomplished by using the relative offset of the first detected synchronization patterns in each pair of data channels as a measure of the relative locations of write elements producing the synchronization patterns and read elements accessing the synchronization patterns. This relative offset is then used to correct subsequent synchronization patterns. This relative offset is then used to correct subsequent synchronization pattern readings taken from the data channel pair.
