In one embodiment, an encoder reads a set of data from memory cells to obtain retrieved data influenced by one or more distortion mechanisms as a result of having been stored. The vibration damper comprises a flexible and resilient, annular damper member having a first end portion connected to a first ring member, and a second opposite end portion connected to a second ring member. The gain controlling unit is configured to output a control signal to the radio frequency signal attenuation circuitry and intermediate frequency processing circuitry. An optimum memory capacity is allocated to the first pipeline if possible.
