Abstract: An optical disk (10) includes several tracks (21-23, 121-125) that each include a series of optical data elements (29, 39). Each optical data element includes several reflective surfaces (31-34, 41-44) with respective different orientations that represent stored information. A detection system (210) directs a beam from a laser (217) onto successive optical data elements. The multiple reflective surfaces of each optical data element produce multiple reflected sub-beams that are imaged onto respective portions of a detector (219, 501, 541). The position of each sub-beam on the corresponding portion of the detector is determined, to thereby identify the orientation of the corresponding reflective surface and thus the stored information represented by that surface.

Abstract: A head includes a bearing surface portion disposed between two transition surface portions which progressively diverge away from a plane containing the bearing surface portion. The bearing surface portion and transition surface portions collectively form a generally continuous surface which is substantially free of abrupt discontinuities in a head travel direction. A method of making the head involves use of a gray-scale mask to pattern a photoresist on a substrate, after which the photoresist is developed and the substrate is etched through the photoresist in order to create on the substrate a three-dimensional surface which includes the bearing surface portion and transition surface portions.

Abstract: A data storage apparatus (10) includes a drive (13) which can removably receive a cartridge (12) that contains a rotatable hard disk (17). The drive has a read/write head (38) supported for movement between a position adjacent an information storage surface (21) on the disk, and a position engaging a cleaning surface (52, 118) located within the drive. A vibrator (56, 112) effects vibration of the cleaning surface while it engages the head, in order to provide efficient and effective cleaning of an air bearing surface on the head, including shallow recesses of this surface.

Abstract: A media serial number (MS#) for a removable data storage cartridge (22) is asymmetrically encrypted using a private key (106) from a key list (103) which never leaves the factory. This factory encrypted value (FEMS#) is stored in a secure memory device (46) in the cartridge, along with an identifier (FKI#). A drive (21) can obtain the encrypted value and associated identifier from the memory device, and pass them to a requesting program (76), which has a list (176) that it accesses with the identifier to obtain a public key it then uses to decrypt the information. An additional feature involves a second level of asymmetric encryption using additional lists of public and private keys. Another feature permits the requesting program to include in its request a random number, which is subsequently included with the information encrypted at the second level.

Abstract: A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region. The written first data is not accepted where the portions of the body are indelibly altered. Accordingly, the read second data corresponds to the written first data with segments thereof missing. The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

The system includes driver software of a host as an interface between a storage device and the third party software application, the storage device and the unique medium. The system enables authentication of the link between the third party application and the driver software by providing third party application developers a toolkit or API for interacting with the driver software. The toolkit includes means to request and decrypt an encrypted driver software digital signature previously generated based on the host's driver software and to compare the digital signature with a second digital signature generated at runtime based on the host's driver software.

Abstract: A data storage disk having a latent illuminance discrimination marker for determining whether the data storage disk is suitable for use in a disk drive. A light source illuminates the marker and the marker emits illuminance, preferably as phosphorescence. A detector detects the emitted illuminance, and a predetermined characteristic of the marker in the frequency domain is determined. The frequency domain response may be either a phase response or an amplitude response, or both. The frequency domain response provides identification of different types or generations of data storage disks or provides a secure keying mechanism for authorized access to proprietary software.

Abstract: A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region.

The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

Abstract: A disk cartridge has a various means for clearly delineating the cartridge from foreign objects which may cause damage to a disk drive. In one embodiment. one or more serial reflectors are embedded within a cartridge so as to return a reflected illuminance pattern distinguishable from a flat specular or flat diffuse surface. In another embodiment, optical pipes carry light from an disk drive mounted emitter to a location where the light is detected by the drive such that the light is not mistaken for reflective light. In another embodiment, a light emitting source such as an LED is embedded in a cartridge such that the intensity of light emitted from the LED in cooperation with reflected light is sufficiently intense to identify the cartridge as a valid cartridge. These embodiments may be rotatable so that a single cartridge may be compatible with more than one drive type.
