DATA STORAGE DEVICE WITH DATA PADDING AND SAFE AND EFFICIENT ALIGNMENT OF DATA ZONES WITH DATA CONTAINERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17850945 titled 'DATA STORAGE DEVICE WITH DATA PADDING AND SAFE AND EFFICIENT ALIGNMENT OF DATA ZONES WITH DATA CONTAINERS

Simplified Explanation

The patent application describes a data storage device that includes disks, an actuator mechanism, and processing devices. The processing devices are designed to detect a criterion for inserting padding on the recording medium near the data containers to be written. The containers are used to assign logic blocks and store data in an interleaved pattern across sectors based on a distributed sector encoding scheme. The criterion for inserting padding is detected by identifying a mismatch in size between a zone and the number of containers needed to write that zone. Mapping indicators are then inserted to indicate the presence of padding blocks near the containers.

• The patent application is for a data storage device with improved data writing efficiency.
• It introduces the concept of inserting padding blocks on the recording medium to optimize the allocation of data containers.
• The device uses a distributed sector encoding scheme to store data in an interleaved pattern across sectors.
• The processing devices detect a criterion for inserting padding by identifying a size mismatch between a zone and the number of containers needed to write that zone.
• Mapping indicators are inserted to indicate the presence of padding blocks near the containers.

Potential Applications

• This technology can be applied in various data storage devices such as hard disk drives and solid-state drives.
• It can improve the efficiency and performance of data writing processes in these devices.
• The optimized allocation of data containers can lead to faster data access and retrieval.

Problems Solved

• The technology solves the problem of inefficient data writing in data storage devices.
• It addresses the issue of mismatched sizes between zones and the number of containers needed to write them.
• The introduction of padding blocks and mapping indicators helps optimize the allocation of data containers.

Benefits

• The technology improves the overall efficiency and performance of data storage devices.
• It allows for faster data access and retrieval due to optimized data writing processes.
• The use of padding blocks and mapping indicators ensures efficient allocation of data containers.

Original Abstract Submitted

Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position heads proximate to a recording medium of the disks; and one or more processing devices. The processing devices are configured to detect a criterion for inserting padding on the recording medium proximate to data containers to be written to the recording medium, the containers configured for assigning logic blocks to the containers, the logic blocks configured to store data to be written in an interleaved pattern across sectors based on a distributed sector encoding scheme, wherein detecting the criterion comprises detecting a mismatch in size between at least a portion of a zone and an integer number of containers in which to write the at least a portion of the zone; and insert mapping indicators to a mapping to indicate padding blocks proximate to the containers.
