| titleOfInvention | Read/write head buffer |
| abstract | The read/write head buffer provides a buffer memory (207) for each read/write head (110-0) in the rotating media data storage system (120) that stores the entire track of data that includes the requested data record. Thus, the read/write head buffer retrieves the requested data record independent of the control module (106) so that a seek request from the processor (100) can be handled as soon as the beginning of the next data record stored on the track is positioned below the associated read/write head (110-0). The entire track is thereby staged faster on the average than the time to retrieve the requested data record. The read/write head buffer includes an address mark detection circuit (214) to identify the beginning of the data field in each data record. The address mark is a predetermined data pattern of n bits that is written on the track a predetermined distance in advance of the data field of the data record. The address mark detection circuit (214) compares the n data bits most recently read from the track with this predetermined data pattern of n bits as stored in memory. Once a match is detected, the buffer (207) is enabled to store the next data record written on the track and all subsequent data records on the track. |
