摘要： A hard disk drive assembly that includes a device for limiting a movement of a head of a head gimbal assembly from a surface of a disk. The head is coupled to the disk and attached to a suspension of the head gimbal assembly. The invented device limits a distance that the head can move away from a surface of the disk. Limiting the distance that the head can move away from the surface of the disk, may reduce the impact force associated with the head slapping the disk, which may reduce damage associated with head slapping.

摘要： The present invention relates to a record carrier for storing a digital work (DW). The record carrier (10) comprises access information (KLT) for gaining access to the digital work and a secondary channel (HC) in which secondary channel information (KLK) is stored which is used for encrypting, decrypting or verifying the access information (KLT). In order to prevent, hinder or discourage tampering with the access information (KLT), the secondary channel (HC) is stored on the record carrier on substantially the same physical location as the access information (KLT). In a preferred embodiment, the secondary channel information (KLK) is changed when the access information (KLT) has changed. This realizes a record carrier for which a replay-attack is prevented. The invention further relates to a method for recording a digital work on a record carrier, a device for recording and a device for reading.

摘要： The present invention provides a magnetic recording and reproducing apparatus, a magnetic recording and reproducing method, and a thin film magnetic head that enable a good contact between elements and a recording medium with a reduced track pitch even if the number of head channels is increased, thereby realizing high recording density and high transfer rate. At least one multitrack write head having N (N is an integer of 2 or more) write elements arranged along a track width direction in an integral fashion and at least one multitrack read head having L (L is an integer equal to or more than N) read elements arranged along the track width direction in an integral fashion are formed on the rotary drum. The multitrack write head writes signals to a group of N tracks aligned parallel on the magnetic tape during one rotation of the rotary drum, and the multitrack read head reads the group of N signal tracks by the use of any one of the L read elements.

摘要： Novel, quick, and reliable detection methods for determining the authenticity of optical and/or audio disc articles (such as compact discs, digital video discs, CD-ROM discs, and the like) are provided. Such a method basically entails the incorporation of an identifier or marking means within the edges of target optical discs or within any other portion of a target disc such that exposure to non-visible light sources will provide the desired identification upon irradiation or detection of the marking means therein. Such an identifier or marking agent thus may be utilized in conjunction with a transparent holding case whereby the needed light source may be exposed through the transparent walls thereof to permit detection of counterfeit or authentic discs without requiring opening of the case itself. Such a method may also be utilized for discs that are removed from or have not been placed and sealed within such a case as well. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention as are novel storage unit configurations to maximize the benefits of the transparent properties thereof.
