ABSTRACT:
The invention provides a read-while-write recording system for a linear data storage medium, such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of separate sliders for the read and write elements, and separate actuators to control the positioning of the sliders. Each of the sliders may also include servo elements to read servo marks. In this manner, the write elements of a first slider can be positioned independently from the read elements of a second slider in order to achieve improved head positioning with respect to data tracks on the linear data storage medium.
