Abstract
Techniques are provided for performing bit-locked operations on media. A first control signal is received from a first source, and a second control signal is generated at a second source in response to receiving the first control signal. The media is accessed according to the second control signal. One or more synchronization markers are located during the accessing of the media, and bit-level synchronization between the second source and the media is achieved based, at least partially, on the one or more synchronization markers. A control operation is performed on the media with bit-level synchrony between the second source and the media.
Claims20
A method for accessing a medium, the method comprising:
- receiving, using control circuitry, a first control signal associated with a first level of accuracy;
- performing synchronization with the medium based on a plurality of synchronization markers in response to receiving the first control signal;
- generating, using the control circuitry, a second control signal associated with a second level of accuracy, wherein the second level of accuracy corresponds to bit-level accuracy, and the second level of accuracy is higher than the first level of accuracy;
- and
- accessing, using the control circuitry, the medium based on the second control signal.
A system for accessing a medium, the system comprising:
- interface circuitry configured to receive a first control signal associated with a first level of accuracy;
- synchronization circuitry configured to perform synchronization with the medium based on a plurality of synchronization markers in response to receiving the first control signal;
- and
- control circuitry configured to:
- generate a second control signal associated with a second level of accuracy, wherein the second level of accuracy corresponds to bit-level accuracy, and the second level of accuracy is higher than the first level of accuracy;
- and
- access the medium based on the second control signal.
