Multiple virtual preamps in a single die

Methods, apparatuses, and systems for allowing a single-die preamp to act as two or more virtual preamps for reading or writing data through multiple heads or elements concurrently. A selection register of a preamplifier is set to enable access to a primary register map. Values of registers in the primary register map are set to program a primary preamp channel for performing read or write operations to a first head. The selection register is then set to enable access to a secondary register map, and values of registers in the secondary register map are set to program a secondary preamp channel for performing read or write operations to a second head. Read or write operations can be performed to the first head through the primary preamp channel at a same time that read or write operations are performed to the second head through the second preamp channel.
