Abstract: A storage system includes network monitoring device having NIC coupled to network and configured to capture raw data packets. The system further includes 4 data repositories. A first repository stores captured packets. A second repository stores captured packets' metadata. A third repository stores captured packets' and metadata's timestamp indexed data. A fourth repository stores captured packets' data flow. The storage system further includes a storage engine coupled to the repositories. The storage engine receives packet search criteria specifying at least a first time range. Data flow information associated with the search criteria is retrieved from the fourth repository. The retrieved data flow information is associated with a second, narrower, time range. Metadata information associated with the second time range is retrieved from the second repository using corresponding timestamp indexed data.

Abstract: A method for forming a magnetic sensor includes: forming a hard mask film on a tantalum nitride film; forming a patterned photoresist layer on the hard mask film; implementing an isotropic dry etching process to the hard mask film by taking the photoresist layer as a mask, so as to form a hard mask layer; and implementing an etching process to the tantalum nitride film and the magnetic film by taking the hard mask layer as a mask, so as to form a tantalum nitride layer and a magnetic resistive layer. As an isotropic dry etching process is implemented to the hard mask film, the hard mask film located which is above the other sidewalls and is not used for forming the magnetic sensor can be effectively removed. In addition, shadow effect will not take place, thus dimension of the magnetic sensor formed is able to be easily controlled.

The DARC layer can prevent the formation of tantalum-containing polymeric substances from a reaction between the TaN layer and the photoresist during the intensified ashing process.
