Abstract: A data storage device exhibiting reduced pad regions includes a read/write channel to convert transduced waveforms from a storage medium into recovered digital information. The recovered digital information is communicated from the read/write channel to a controller. The read/write channel includes an analog stage and a digital stage, which function independently. While the digital stage is engaged in the task of recovering servo data, the analog stage may be engaged in the task of recovering user data. Initially, the controller generates a control signal commanding the read/write channel to read and recover servo data. In the wake of the last unit of servo data having been processed by the analog stage of the read/write channel, the controller commands the read/write channel to read user data from the disc. Therefore, the analog stage of the read/write channel reads user data, while the digital stage finishes processing the servo data.
