System and method for handling events in an optical disc drive

A method for handling an event in a control system for an optical disc drive, comprising:

• receiving the event, wherein the event pertains to an error condition in the disc drive;
• determining whether a previous event was received for the same error condition;
• determining whether excessive recovery attempts have been made based on at least one of:
• the time between the events received for the same event, and the number of events received for the same error condition;
• and
• initiating recovery from an error condition associated with the event if excessive recovery attempts have not already been made for the same error condition.

A system for handling events in a control system for an optical disc drive, comprising:

• a set of control system instructions, wherein the set of control system instructions are operable to:
• perform one or more commanded operations on optical media in the disc drive;
• receive an event pertaining to an error condition with the disc drive;
• initiate a recovery attempt from the error condition;
• suspend processing of the one or more commanded operations;
• determine whether the recovery attempt was successful;
• resume processing the one or more commanded operations if the recovery attempt was successful;
• determine whether a previous event was received for the same error condition;
• determine whether excessive recovery attempts have been initiated based on at least one of:
• the time between the events received for the same error condition, and
• the number of events received for the same error condition;
• and wherein the system instructions are further operable to
• initiate recovery from the error condition if excessive recovery attempts have not already been made for the same error condition.

• wherein the event indicates at least one of:
• a notify event, a spin event, a tracking event, a focus event, a switches event a timeout event, a performance event, or a command abort event, and wherein the set of control system instructions are further operable to:
• dynamically recalibrate the disc drive when the performance event is received.
