    摘要: A data storage device is disclosed comprising a non-volatile memory powered by a supply voltage. The supply voltage is compared to a power loss threshold, and when the supply voltage falls below the power loss threshold, a power loss event is detected and an emergency operation is executed. The power loss threshold is decreased, and after an interval the power loss threshold is increased.

    摘要: An embodiment of a circuit for maintaining voltage at a voltage bus after a power loss in a hard disk drive system. HDD systems may suddenly lose power and specific tasks, such as parking the read/write head and storing state data may be accomplished using a power generated from back EMF of a motor that is still turning. During the power loss sequence, a drive controller may drive a power chipset to regulate the voltage at a voltage bus so as to conserve power as much as possible. In this manner, the drive circuit may regulate the voltage via a drive algorithm to be just above a threshold voltage (typically 4.4 V) while the HDD system is storing state data, but apply other algorithm for other situations, such as parking the read/write head. Various drive algorithms may be tailored to provide a specific sequence of voltage bus regulation techniques suited to specific applications.

    摘要: A method for recovering video data in a disk when a reading error occurs is provided. First, the disk is scanned to obtain a next writable address (NWA) of a last video chapter previously recorded into the disk. An end address of a successfully recorded video chapter is then read from a specific area of the disk and stored into a memory. Next, when a disk player/recorder is requested to read content of data according to the NWA, the disk player/recorder determines whether the content of the data is a file system. If the content of the data is not a file system, the NWA obtained by scanning the disk is replaced with the end address read from the specific area to read the file system, so as to recover the video data in the disk. Thereby, the video data in the disk can be protected.

    摘要: With a storage system including a drive and a controller, which are connected to each other via cables, and with a method for controlling the storage system, an emergency power supply voltage for a power failure at the drive is multiplexed at the controller with a first signal to be sent to the drive, and the resultant emergency power supply voltage is sent via the cable to the drive. When a power failure occurs at the drive, the drive is powered with the emergency power supply voltage sent from the controller, and specified power failure information is multiplexed at the drive with a second signal to be sent to the controller, and the resultant power failure information is then sent via the cable to the controller; and specified processing is executed at the controller in response to the power failure information sent from the drive via the cable. Accordingly, it is possible to realize a storage system and the controlling method therefor that are adequate for practical applications and can sufficiently cope with drive power failures without the need for complication and upsizing of the entire system configuration.

    摘要: An HDD is divided into a segment area storing multimedia data, an information file area storing an information file of a file, and a system information area storing a system information file. Storage of the system information file in the system information area and storage of the information file in the information file area are performed every prescribed time (X seconds), instead of a time point when recording and/or reproduction is stopped. If an apparatus suddenly stops, a location where damage is likely in the HDD can be detected by referring to the information file area and the system information area.
