Patent number: 11610603Abstract: A data storage device can have one or more rotating data media with data tracks that are radially disposed from a central spindle. The data tracks may be logically divided into multiple regions while a write strategy is generated with a region module to set a sequence of different regions for future data writes. Receipt of a data write request to the data storage media from a host can prompt the region module to classify the data write request as a sequential or random write in order to intelligently select a region to satisfy the data write request based on the write strategy to maximize data writing consistency for data associated with the data write request.Type: GrantFiled: April 2, 2021Date of Patent: March 21, 2023Assignee: Seagate Technology LLCInventors: Chee Hou Peng, Ajay Narayan Kulkarni, Harry Tiotantra, KayHee Tang, WenXiang Xie

Publication number: 20210382775Abstract: The present disclosure provides systems and methods for classifying incidents based on determining an odds ratio that represents a likelihood of an incident being related to the problem, classifying incidents based on determining a decision tree that forms branches based on whether a feature is present in the incident, and predicting whether a new incident is related to a problem. Features may be extracted from a set of incidents (e.g., that are reported over a certain time period) that include incidents related to a problem and incidents not related to the problem. The incidents related to the problem and a portion of the incidents not related to the problem may be used to train a logistic regression model or generate a decision tree. The trained logistic regression model may be used to determine the odds ratios or predict whether a new incident is related to a problem.Type: ApplicationFiled: August 24, 2021Publication date: December 9, 2021Inventors: Lingzhu Li, Abhay Narayan Kulkarni, Matthew David Lloyd

Patent number: 11157364Abstract: ECC is used to for controlling errors in blocks of data by including a measure of redundancy within the data for recovering one or more unreadable portions of the data. A codeword includes at least a message and one or more additional ECC blocks. In the event of an unreadable sector, the ECC is decoded and used to recover the erroneous or missing portion(s) of the message. With disc access parallelism, ECCs can now be distributed across data storage surfaces and/or multiple storage platters. Distribution of ECCs increases the likelihood of recovering data from a head failure or from burst errors on a data storage surface and adds the option to decode parity after only 1/n revolutions.Type: GrantFiled: June 29, 2020Date of Patent: October 26, 2021Assignee: SEAGATE TECHNOLOGY LLCInventors: David Andrew Rice, Ajay Narayan Kulkarni, Brian T.
