Abstract
A system is provided that has the ability to perform simultaneous parallel read and write operations with a plurality of transducing heads that transduce data with a storage medium. The system includes a preamplifier circuit and a read channel. The read channel includes a serializer circuit coupled to the preamplifier circuit to receive parallel data-signals and convert those signals into a serial data signal that is provided to a read channel core/controller. The read channel also includes a deserializer circuit coupled to the preamplifier circuit that converts serial write control signals from the read channel core/controller into parallel write control signals that are transmitted to the preamplifier circuit for controlling write operations.

A system for performing simultaneous read and write operations with a plurality of transducing heads for transducing data with a storage medium, the system comprising:
- a preamplifier circuit for coupling to the plurality of transducing heads, the preamplifier circuit being operable to:
- receive read signals from the plurality of transducing heads;
- transmit parallel data signals representing the read signals received from the plurality of transducing heads;
- receive parallel write control signals;
- and
- transmit write signals to the plurality of transducing heads, the write signals being based on the write control signals received;
- and
- a read channel comprising:
- a serializer circuit coupled to the preamplifier circuit to receive the parallel data signals and convert those signals into a serial data signal;
- a read channel core/controller for interpreting the serial data signal and for providing a serial write control signal;
- and
- a deserializer circuit coupled to the read channel core/controller to convert the serial write control signal into the parallel write control signals that are transmitted to the preamplifier circuit.
A method of performing simultaneous parallel read operations in an electronic data storage system, comprising:
- receiving parallel read signals from a plurality of transducing heads that read data from a medium;
- providing parallel data signals representing the read signals received from the plurality of transducing heads;
- converting the parallel data signals into a serial data signal;
- interpreting the serial data signal to recover information stored on the medium.
A method of performing simultaneous parallel write operations in an electronic data storage system, comprising:
- generating a serial write control signal based on a write command;
- converting the serial write control signal into parallel write control signals;
- transmitting write signals to a plurality of transducing heads, the write signals driving the transducing heads to write data to a medium and being based on the parallel write control signals.
