Abstract: A system and method is disclosed for improved operation of a data storage device such as a hard disk drive. The overhead for data rewriting may be reduced by the periodic remapping of logical block addresses to avoid excessive adjacent track interference effects on data blocks having lower data writing rates. It may employ the indirection system to remap data “hot spots” to new locations neighboring on spare data blocks. In circumstances where it is not possible to write data next to spare data blocks, the active LBA may be periodically moved after a predefined number of write operations.

Abstract: The invention relates to a printer which can print both text and bar code data on an elongated web-like tape. The printer is provided with a display having a first display mode in which both text data and bar code data are displayed. A bar code display unit is provided to advise the user when the cursor is assigned to bar code data in the first display mode. A second display mode can also be provided. In the second display mode, only the bar code data is displayed and only it can be entered and edited. When characters comprising either text data or bar code data are entered, they are placed sequentially in an input buffer, which comprises a first area of a storage device. The start and end positions of the bar code data within the input buffer are stored in a second area of the storage device. During printing operations, the position of each character in the input buffer is compared to the start and end positions to determine whether that particular character is to be printed as text or as a bar code.
