Abstract
Aspects of the disclosure provide a method. The method includes receiving regional quality information of a region on a storage medium, and adjusting a fill level threshold of a buffer based on the regional quality information. The fill level threshold is used to trigger filling the buffer with data read from the region.
Claims15
A method, comprising:
- scanning a storage medium to determine regional quality information when a fill level of a buffer is above a fill level threshold, the fill level threshold being used to trigger filling the buffer with data read from a region of the storage medium;
- receiving the regional quality information of the region;
- and
- adjusting the fill level threshold of the buffer based on the regional quality information.
1 more element
A method, comprising:
- scanning a storage medium to determine regional quality information and reading data from a region on the storage medium when a fill level of a buffer is above a fill level threshold, the fill level threshold being used to trigger filling the buffer with the data;
- adjusting the fill level threshold of the buffer based on the regional quality information;
- storing the data in a temporary memory space;
- and
- moving the data from the temporary memory space into the buffer when the region becomes a target reading region.
2 more elements
A circuit, comprising:
- a memory having a portion being allocated as a buffer to buffer data read from a storage medium, and to provide the data to a host device;
- and
- a controller circuit configured to cause a scan of the storage medium when a fill level of the buffer is above a fill level threshold to determine regional quality information of a region on the storage medium, the fill level threshold being used to trigger filling the buffer with the data read from the region, and receive the regional quality information, and adjust the fill level threshold based on the regional quality information.
