Data Coding for storage systems based on generalized concatenated codes

摘要

1. A method comprising the steps of: - receiving data in a data storage system, - forming codewords from the received data, wherein the code words are calculated using a generalized concatenated code, and each codeword comprises a code, wherein the symbols comprise information symbols and control characters; u retain codewords on an array of disks associated with the storage system dannyh.2. A method according to Claim. 1, wherein the step of storing further comprises the step of storing the received symbols i-codewords formed on i-ROM array that diskov.3. A method according to Claim. 1, wherein the step of forming codewords further comprises the step of generating codewords comprising internal and external codes kody.4. A method according to claim. 3, wherein the codewords based on the outer code comprise binary linear kody.5. A method according to claim. 3, wherein the codewords based inner code contain polar kody.6.
