摘要： Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only. When a stray field in a direction horizontal in relation to the recording medium is applied, the magnetic field acting on the recording medium is removed by the cover of the device comprising a magnetic component.
摘要翻译：本发明的实施例不管施加杂散场的方向如何，都防止磁化或退磁的发生发生到记录磁化。在一个实施例中，一种用于数据存储系统的装置包括在主极附近具有磁场屏蔽的头部，以及使用具有磁场屏蔽效应的组成材料穿过该盖的装置的盖，或者在的一部分。当施加与记录介质垂直的方向上的杂散场时，通过安装在主极附近的磁场屏蔽来减轻磁场的影响。在这种情况下，只需要使磁场屏蔽形成为仅在垂直方向上去除杂散场的最佳形状。当施加相对于记录介质的水平方向的杂散场时，作用在记录介质上的磁场被包括磁性部件的装置的盖子去除。

摘要： In a disk array system for RAID (level 5) to improve a process performance by dispersing data, the overhead during data writing operation is reduced. Even when write data are used to rewrite data #1 to data #4, which have already been written at address SADR 2, SADR 2, SADR1 and SADR 3 within drives as data belonging to mutually different parity groups, these data are considered as new write data, and then these new write data are written in parallel into, for instance, an empty region in the drive at the address SADR 4. The updated old data or the updated old parity data are not read out. The invalidation flags for the updated old data are registered into an address conversion table. The subsequent data readout operation is carried out from a newly written region. When all of data within the original parity group are invalidated, the region holding this group is used as an empty region. The valid data within the parity group, which have been partially invalidated, are replaced at a proper timing. In other words, these valid data are acquired to produce a new parity data group which will then be stored into the empty region. In the above operation, it is assumed that a length of data transferred from a host unit is constant, and data belonging to one parity data group has this constant length.
摘要翻译：在用于通过分散数据来提高处理性能的用于RAID（5级）的磁盘阵列系统中，减少了数据写入操作期间的开销。即使使用写入数据将数据＃1重写到已经写入驱动器内的地址SADR 2，SADR 2，SADR1和SADR 3的数据＃4，作为属于相互不同的奇偶校验组的数据，这些数据被认为是新的写入数据，然后将这些新的写入数据并行写入到例如地址SADR4的驱动器中的空白区域。更新的旧数据或更新的旧奇偶校验数据不被读出。更新的旧数据的无效标志被注册到地址转换表中。随后的数据读出操作是从新写入的区域进行的。当原始奇偶校验组中的所有数据无效时，保持该组的区域被用作空白区域。奇偶校验组中的有效数据已被部分无效，在适当的时机被替换。换句话说，获取这些有效数据以产生新的奇偶校验数据组，然后将其存储到空区域中。在上述操作中，假设从主机单元传送的数据的长度是恒定的，属于一个奇偶校验数据组的数据具有这个恒定长度。
