20100030987 | DATA STORING LOCATION MANAGING METHOD AND DATA STORAGE SYSTEM - A data storing location managing method including generating an access frequency of a storing area accessed in a first storage apparatus according to a command received, copying data stored in the storing area of the first storage apparatus to a storing area of a second storage apparatus when the access frequency of the storing area of the first storage apparatus is greater than a reference value, and replacing location information of the storing area of the first storage apparatus with location information of the storing area of the second storage apparatus. | 02-04-2010 |
20100070689 | HYBRID HARD DISK DRIVE TO RAPIDLY READ FILES HAVING SPECIFIED CONDITIONS, METHOD OF CONTROLLING THE HYBRID HARD DISK DRIVE, AND RECORDING MEDIUM FOR THE HYBRID HARD DISK DRIVE - A method of controlling a hybrid hard disk drive. The method includes receiving a read command from a host; searching metadata of a file to be read; determining whether the metadata satisfies a predetermined setup condition; and if the metadata satisfies the setup conditions, copying the file to be read, from a first storage device and storing the file in a second storage device. | 03-18-2010 |
20100070699 | HYBRID HARD DISK DRIVE CAPABLE OF STORING FILE HAVING SPECIFIED CONDITION, A METHOD OF CONTROLLING THE SAME, AND RECORDING MEDIUM ADAPTED FOR EXECUTING THE METHOD - A method of controlling a hybrid hard disk drive includes receiving a write command from a host; extracting metadata of a file to be written, determining whether the metadata satisfies a predetermined set condition, and storing the file to be written in a first storage device when the metadata satisfies the set condition. | 03-18-2010 |
20100325384 | DATA STORAGE MEDIUM ACCESSING METHOD, DATA STORAGE DEVICE AND RECORDING MEDIUM TO PERFORM THE DATA STORAGE MEDIUM ACCESSING METHOD - Provided are a data storage medium accessing method of accessing a data storage medium of a data storage device according to a virtual address (VA), the data storage device to access the data storage medium according to the VA, and a computer readable recording medium having recorded thereon a program to access the data storage medium accessing method. The data storage medium accessing method includes the operations of converting a logical block address (LBA) included in a command received from a host into a VA and converting the VA into a real address of a data storage medium included in a data storage device, and accessing the data storage medium using the real address, wherein the VA is an address that is based on a reserved block of the data storage medium in a data write operation, wherein the reserved block is a valid block that is ready to have data written thereto, and wherein a current location of a head included in the data storage device during the data write operation is set according to the reserved block. | 12-23-2010 |
20110093645 | METHOD AND APPARATUS TO RECORD DATA, METHOD AND APPARATUS TO REPRODUCE DATA, AND RECORDING MEDIUM - A data recording method including, when moving data stored in a cache to a data storage medium, selecting one cache area from an extended cache area group of the data storage medium by using managing information of a translation layer, moving the data stored in the cache to the selected cache area by using a physical address of the data storage medium on the selected cache area, and updating the managing information of the translation layer, wherein the managing information of the translation layer includes a physical block address-based address of the extended cache area group in the data storage medium. | 04-21-2011 |
20110197035 | DATA STORAGE DEVICE, STORING MEDIUM ACCESS METHOD AND STORING MEDIUM THEREOF - A data storage device including a storing medium to shingle write and a controller to access the storing medium so that data is sequentially written on the storing medium using a mapping table based on Logical Block Address (LBA) included in a write command. | 08-11-2011 |
20130031296 | SYSTEM AND METHOD FOR MANAGING ADDRESS MAPPING INFORMATION DUE TO ABNORMAL POWER EVENTS - A method and apparatus for managing address map information are disclosed. In one embodiment, an apparatus may comprise a processor configured to store address map changes to a first data storage medium, save the address map changes to a nonvolatile data storage medium when an abnormal power state is detected, and when the power state is no longer abnormal retrieve the last saved address map information and address map changes and update the address map information using the address map changes. The apparatus may be configured to retrieve the instructions for the processor operation over a network connection. | 01-31-2013 |
20130031317 | METHOD AND APPARATUS FOR REDIRECTING DATA WRITES - Apparatuses and methods for redirecting data writes are disclosed. In one embodiment a controller may be configured to receive a command including write data and address data identifying a target zone of a data storage medium; determine whether the target zone contains sufficient available data sectors to store the write data; and record the write data to a common area of a different zone when the target zone does not contain sufficient available data sectors, the common area available to store data when a target zone lacks sufficient available data sectors. In another embodiment, a method may comprise receiving a write command identifying a target zone of a data storage medium; determining whether the target zone contains sufficient available data sectors to store the write data; and recording the write data to a common area of a different zone when the target zone does not contain sufficient available data sectors. | 01-31-2013 |
20130290668 | METHOD AND APPARATUS FOR ADJUSTABLE VIRTUAL ADDRESSING FOR DATA STORAGE - Methods and apparatuses for adjusting the size of a virtual band or virtual zone of a storage medium are provided. In one embodiment, an apparatus may comprise a data storage device including a data storage medium having a physical zone; and a processor configured to receive a virtual addressing adjustment command, and adjust a number of virtual addresses in a virtual band mapped to the physical zone based on the virtual addressing adjustment command. In another embodiment, a method may comprise providing a data storage device configured to implement virtual addresses associated with a virtual band mapped to a physical zone of a data storage medium of the data storage device, receiving at the data storage device a virtual addressing adjustment command, and adjusting a number of virtual addresses in a virtual band based on the virtual addressing adjustment command. | 10-31-2013 |
