A disk drive is disclosed comprising a disk having a plurality of data sectors, wherein a physical block address (PBA) is associated with each data sector. When a write command is received from a host to write user data to the disk, and the write command comprises an unformatted logical block address (LBA), the user data is written to a first data sector, and the first data sector is write verified. A second data sector is defect scanned, and after the second data sector passes the defect scan, the user data is migrated from the first data sector to the second data sector and the LBA is formatted to the second data sector.

An audio/video information recording and reproducing apparatus and method are provided, in which a post-recording function can be realized on an optical disc easily even with an inexpensive disc drive having a seek time at a relative low speed. In the case of recording a video file, the video file is recorded on an optical disc continuously for a period of time related to three times or more the seek time. Then, in the case of recording an audio for lip-sync, the audio for lip-sync is recorded continuously by a predetermined data size, and simultaneously, the recorded video file is reproduced, whereby real-time continuous reproduction and recording are performed simultaneously. Because of this, in the case of reproducing the audio for lip-sync, simultaneous reproduction of a video file and an audio file can be assured.

Disclosed are a method and apparatus for storing digital content in a storage device. A content key, which is a key used by a host for encrypting content when the content is stored to a storage device connected to the host, is encrypted by using a storage key of the storage device. The encrypted content key and encrypted content are stored in the storage device, and the host only stores storage keys. Thus, quantity of information maintained by the host can be reduced. Also, when a storage key is stored in a portable security component (PSC), portability and mobility of content bound to a single host may be improved.

A library of a PC is easily synchronized with recorded contents of a disc loaded into a recording and reproducing apparatus (PD). The PC has a dynamic group and a database. Contents of the dynamic group are, dynamically changed. The dynamic group is correlated with the ID of the disc on which the contents of the dynamic group have been recorded. When the CP and the PD are connected, the ID of the disc loaded into the PD is read. The database is referenced for the ID of the disc. When there is a corresponding dynamic group, the dynamic group is compared with the recorded contents of the disc. Contents that exist in the dynamic group and that do not exist on the disc are checked out to the disc. In contrast, contents that exist on the disc and that do not exist in the dynamic group are checked in to the PC. In addition, the reproduction order of contents of the dynamic group is reflected to contents of the disc. The user can synchronize the recorded contents of the disc with the library of the PC only by connecting the PC and the PD.

The remote control unit includes a remote control computer system and remote control software that can be used to control the recorder/player unit. The system can be used to automatically copy all of the audio on CDs into memory on the recorder/player, to control multiple pieces of audio and video equipment, and to download and store new music from the Internet.

A transfer apparatus for transferring data which achieves balancing in profit and loss between a proprietor of copyright and a user includes an instruction section for providing an instruction of a transfer rate, a transfer control section for variably using one of various transfer control methods for data in response to the transfer rate of the instruction provided by the instruction section, and a billing control section for changing the transfer control method by the transfer control section in response to billing processing performed by a user of the transfer apparatus.

Provided is a method of preventing digital content from being used despite the presence of copy control information. In the method, a security apparatus capable of restricting use of contents generates a nonce with respect to a storage device and stores the nonce in the storage device and a memory separated from the storage device when content is stored in the storage device; updates the nonces stored in the memory and storage device when movement of the content occurs; and permits use of the content only when the nonce of the storage device, which is stored in the memory, is equal to the nonce stored in the storage device if the content is requested for use, thereby preventing a disk cloning attack.

Charging in a reasonable manner for a fee regarding an information recording apparatus recording information into a recording medium. Information received through a tuner or reproduced through a digital reproducing section is converted by a format conversion circuit, supplied to a digital, an analog or a memory card type recording and reproducing section where dubbing is carried out. Such information can be also stored in a storage medium such as a HDD and then supplied and dubbed in the pertinent recording and reproducing section. When the recording medium containing recorded information is unloaded, charging is done through a charging section. Once unloaded, the recording medium can be easily taken out and used, thus such a convenience can be charged as well. In addition, the charging can be done corresponding to a number of recording media containing recorded information. Furthermore, a user can verify whether recording has been carried out properly, before charging.
