摘要： A data storage system comprising a storage device comprising at least one nonvolatile memory, and a controller connected to the storage device through a channel. The memory controller sends part or all of a command, address and data for a next operation to the nonvolatile memory while the nonvolatile memory device is in a busy state. The memory controller then performs a background operation while the nonvolatile memory device remains in the busy state.

摘要： Disclosed is a method of electroplating a Ni—Fe—P alloy using a sulfamate solution and, in particular, a method of electroplating a Ni—Fe—P alloy using a plating solution containing nickel sulfamate, iron sulfamate, phosphorous acid, and a buffer agent. The method is advantageous in that a residual stress of a deposited layer is very low and has stable mechanical properties, and excellent thermal and corrosion resistance because the deposited layer is obtained by electroplating the Ni—Fe—P alloy using the sulfamate solution useful in a high rate plating process. Furthermore, the method can be applied to various parent metals such as stainless steel, Inconel and iron alloys, and to various fields because the chemical compositions of the deposited layer are readily controlled by varying the concentration of the plating solution.

摘要： A data storage system includes data storage including at least one data storage disk driven by a spindle motor and a control circuit coupled to the data storage and configured to be coupled to a main power source and a backup power source. The control circuit is configured to detect failure of the main power source, to responsively write data to the data storage while powered by the backup power source, and to subsequently recharge the backup power source using the spindle motor. The control circuit may be configured to further write data to the data storage using the recharged backup power source. The data storage system may further include a head configured to read and/or write data to or from the at least one data storage disk, and the control circuit may be configured to park the head using the recharged backup power source.
