Abstract
Disclosed are systems, methods, and devices for increasing the storage areal density of a storage device. In one embodiment, a method is disclosed comprising receiving host data, the host data including first data and extra bit data; generating run-length limited (RLL) data by encoding the first data with an RLL encoder; generating a symbol corresponding to at least one bit of the extra bit data; and generating superpositioned data by inserting the symbol within a contiguous section of repeating bits in the RLL-encoded first data.
Claims32
A method comprising:
- receiving, by a processor, first data and second data;
- encoding, by the processor, the first data to generate encoded data;
- generating, by the processor, a symbol corresponding to the second data;
- and
- generating, by the processor, superpositioned data by inserting the symbol within the encoded data.
2 more elements
An apparatus comprising:
- one or more processors;
- and
- a non-transitory memory storing computer-executable instructions therein that, when executed by the processor, cause the apparatus to perform the operations of:
- receiving first data and second data;
- encoding the first data to generate encoded data;
- generating a symbol corresponding to the second data;
- and
- generating superpositioned data by inserting the symbol within the encoded data.
5 more elements
A method comprising:
- receiving, by a processor, data, the data including at least one codeword;
- locating, by the processor, extra bits included in the codeword using a pre-defined preamble pattern;
- demodulating, by the processor, the extra bits to generate an extra bit portion;
- and
- replacing, by the processor, the extra bits in the codeword with the extra bit portion to obtain a second codeword.
