Abstract: PROBLEM TO BE SOLVED: To provide servo-position information encoded by magnetic polarity for a storage medium using magnetism as a base. SOLUTION: A magnetic storage medium includes a magnetic S-N servo band section and a magnetic N-S servo band section. The magnetic S-N servo band section includes a servo track segment, which is initialized by the polarity of the S magnetic pole, and a servo pattern of polarity of the N magnetic pole recorded on the servo track segment which is initialized by the polarity of the S magnetic pole. The magnetic N-S serve band section includes a servo track segment, which is initialized by the polarity of the N magnetic pole, and a servo pattern of the polarity of the S magnetic pole recorded on the servo track segment which is initialized by the polarity of the N magnetic pole. The magnetic S-N servo band section and the magnetic N-S servo band section are relatively recorded on the servo track, and, based on the servo pattern of the polarity of the N magnetic pole and the servo pattern of the polarity of the S magnetic pole, servo-position information encoded by the magnetic polarity is represented.

Abstract: An approach for managing a data package is provided. Network throughput is determined to exceed a threshold. A sender computer determines a hash digest of the data package by using a hash function selected based on central processing unit utilization. If the hash digest is in a sender hash table, then without sending the data package, the sender computer sends the hash digest and an index referring to the hash digest so that a recipient computer can use the index to locate a matching hash digest and the data package in a recipient hash table. If the hash digest is not in the sender hash table, then the sender computer adds the data package and the hash digest to the sender hash table and sends the data package and the hash digest to the second computer to check the integrity of the data package based on the hash digest.

Abstract: Operating a data processing and storage apparatus to perform continuous backup monitoring for a collection of stored file system objects. In response to changes respective to a number of the file system objects, a set of Data Management Application Program Interface (DMAPI) events is created. For each of the events, accessory file system object information relative to a file system object subject to the change is determined. The events are grouped into an event group and a unique group identifier and an overall group size count are assigned to each of the events included in the event group. The events are sent together with the respective accessory file system object information, the respective group identifier and the respective group size to a number of backup clients registered as applications. The backup clients are to process the events together with the respective accessory file system object information, the respective group identifier and the respective group size into a number of backup requests.
