Abstract
According to one embodiment, a method for processing data includes directing first data through a first FIR gain module in response to a determination that the first data is being read from a magnetic tape medium in an asynchronous mode to control FIR gain of the first data. The method also includes directing second data through a second FIR gain module in response to a determination that the second data is being read from the magnetic tape medium in a synchronous mode to control FIR gain of the second data. Other systems and methods for processing data using dynamic gain control with adaptive equalizers are presented according to more embodiments.
Claims20
A system for processing data, the system comprising:
- a controller and logic integrated with and/or executable by the controller, the logic being configured to cause the controller to:
- direct data through either a first finite impulse response (FIR) gain module or a second FIR gain module to control FIR gain of the data,
- wherein the first FIR gain module is utilized when reading the data in an asynchronous mode, and
- wherein the second FIR gain module is utilized when reading the data in a synchronous mode and a FIR gain value of the second FIR gain module is automatically controlled.
A method for processing data in a read channel, the method comprising:
- passing data through either a first finite infinite response (FIR) gain module or a second FIR gain module to control FIR gain of the data,
- wherein the first FIR gain module is utilized when reading the data in an asynchronous mode, and
- wherein the second FIR gain module is utilized when reading the data in a synchronous mode and a FIR gain value of the second FIR gain module is automatically controlled.
A method for processing data, the method comprising:
- directing first data through a first finite impulse response (FIR) gain module in response to a determination that the first data is being read from a magnetic tape medium in an asynchronous mode to control FIR gain of the first data;
- and
- directing second data through a second FIR gain module in response to a determination that the second data is being read from the magnetic tape medium in a synchronous mode to control FIR gain of the second data.
