Flexible on-cylinder limit for drive performance management

One or more processor-readable storage media encoding processor-executable instructions for executing on a computer system a computer process, the computer process comprising:

• generating servo adaptive parameters (SAPs) by heads;
• generating a plurality of read adjust parameters (RAPs) by heads for a plurality of drives;
• generating an interim OCLIM value based on the SAPs by heads and RAPs by zones;
• and
• operating a disc drive write element using the interim OCLIM value.

In a computing environment, a method performed at least in part on at least one processor, the method comprising:

• performing servo certification of a plurality of drives in a storage device to generate servo adaptive parameters (SAPs) by heads;
• generating an interim OCLIM value based on the SAPs by heads and read adjust parameters (RAPs) by zones;
• and
• operating a disc drive write element using the interim OCLIM value.
