Benefits of technology

The patent describes a method of storing data on different types of storage devices, such as disk drives and flash memories, to ensure that the data is always accessible and can be recovered in case of failure. The method takes into account various factors like access rate, resilience to errors, data integrity, storage density, and storage capacity to ensure the best quality of service for each type of storage device. This allows for efficient and effective storage of data on various devices and ensures that the data is always accessible.

Problems solved by technology

The source may be prone to some errors and the target resilient to some errors as well.
At 10 Mbps, this results in approximately 10 seconds between errors.

Abstract

A method of storing data includes receiving general purpose (GP) data and special Error Tolerant or Streaming (ETS) data, storing the GP data using a data storage method, and storing the ETS data using a different data storage method which affects the access rate, resilience to errors, data integrity, storage density, or storage capacity. The storage medium, which can include a disk drive, flash memory, or holographic memory, is utilized differently depending on the required Quality of Service in aspects including block size, storage of error correction codes, utilization of error correction codes, storage area density, physical format pattern, storage verification, or reaction to failed storage verification. For disk drives these differences include spacing between tracks; overlap between tracks; spiral track formatting; concentric track formatting, and size of blocks, and for flash memories these differences include levels per cell and number of cells.

Description

FIELD OF THE INVENTION[0001]This invention is generally related to storage devices, and more particularly storage devices for storing error tolerant or streaming data.BACKGROUND OF THE INVENTION[0002]This invention pertains to the application of a storage device (such as a disk drive, or flash memory, or holographic memory, or any type of data storage) and its use in storing and retrieving user data.[0003]Generally, user data comprises both General Purpose (GP) data and data with special requirements, such as error tolerant or streaming (ETS) data. ETS data is either error tolerant, meaning that the data is still usable even with some errors, or streaming, meaning that each block of data follows the next in a “file”-like format, or both. As such, streaming Audio / Visual (AV) data would serve as an example of ETS data. Streaming AV data might come in the form of an MPEG-4 encoded TV program, for example. TV programs can be error tolerant, because the viewers will generally not mind sm...
