    摘要: A record carrier (1) comprises essentially circular tracks (20) concentrically located around a point of rotation (2). The record carrier (1) is divided into circular zones (4, 5, 6) comprising each m tracks (22), with m being an integer. Each track within a zone is subdivided into n sectors (8), with n being an integer which is constant per zone and which increases as the zone is more remote from the point of rotation (2). Each sector (8) comprises a header portion (9) and a data portion. The header portions (9) in radial direction in each zone are in line. In each zone the condition of m.n = l.k is satisfied, with l being an integer greater than or equal to 2 and being constant for each zone, and with k being an integer.

    摘要: A unique and permanent identifier is provided for removable media. The identifier is preferably recorded in a previously unused or reserved portion of the media and can be generated from a combination of the originating drive serial number and the current date and time with a random number concatenated thereto. When a piece of media is loaded into a drive, the drive examines the reserved area for the presence of an identifier. If not present. the drive generates and records an identifier before performing whatever disk access operations have been requested. If the identifier is present, the drive is prevented from overwriting the identifier with a new one and the disk access operations are performed immediately. Once the media is provided with its identifier, the media, and any errors associated with the media, can be tracked throughout its life.

    摘要: A method and apparatus for ensuring the proper position and orientation of a multi-disk cartridge (100), and for selectively locking the cartridge (100) while it is inserted in a disk drive (400) to prevent withdrawal of the cartridge (100) while the disk drive (400) is conveying one of the cartridge's disks. The disk drive of the invention includes a guide (402) to slidably receive a multi-disk cartridge (100). When the cartridge (100) is inserted in the guide (402), presence of the cartridge (100) in the drive (400) is detected by a position sensor (414). Having detected the presence of the cartridge (100), an orientation sensor (416) determines whether the cartridge (100) has been oriented properly. This prevents upside-down insertion of the cartridge (100), for example. With the cartridge (100) fully inserted into the guide (402) in a proper orientation, a locking mechanism (422) serves to lock the cartridge (100) in place at selected times. The cartridge (100) may be locked in place, for example, at all times when the cartridge (100) is inserted into the guide (402), or merely during sensitive operations of the disk drive (400).
