Abstract: An improved method and apparatus for data storage on hard disk drives (HDD) is described. The method and apparatus employ sequential data recording techniques ideal for sequential recording applications thus enabling the production of cheaper, more reliable and conveniently accessible systems. The sequential recording method may be employed with arrays of low-cost HDD and/or with the sequential employment of sectors, or groups of sectors, located within the individual HDDs themselves. An important feature of the system is that data are never deleted and so is only ever lost when overwritten with new data. Particular embodiments of the invention describe mirrored data storage systems which also provide for protection against data loss should one or more data storage elements fail.
