How to Encode Binary Words Using RLL(2,7)?

[fran1942]

Hello, I am trying to represent a binary word as different types of encoding. I am OK with all the different forms apart from the last one.
That last step is to represent it as RLL(2,7). However I do not know how to do it. After researching on the internet, it seems very complicated to do this.
Is anyone able to help out with this ?

Thank you kindly for any assistance.

Best article I could find. Scroll down to mid page for RLL (2,7) information. Since the encoding is done at the sector level, usually 512 bytes, there may be some extra bits at the end in order to match the allowed data patterns. The encoder adds the extra bits and the decoder ignores the extra bits:
