摘要： A method and apparatus for detecting and respond to low-amplitude-write/skip-write events in a disc drive. The invention involves characterizing the gain factor of a variable gain amplifier embedded in the read path of a disc drive during at least two instances in which the read head passes over a servo sector, prior to a write event. Next the write event is executed. After the write event, the gain factor employed by the variable gain amplifier is acquired as the read head passes over the following servo sector. Finally, the acquired gain factor is compared to the characterizaton in order to detect a low-amplitude-write/skip-write event.

摘要： Shorts are detected in terminals fed current by a driver connected to the terminals. To detect terminal-to-ground shorts, at least one virtual driver is connected to the driver for processing an output of the driver, and a detector detects if a short has occurred, based on an output of the virtual driver, by detecting when an output of the virtual driver exceeds a first threshold. If the detector detects that the output of the virtual driver has exceeded the first threshold, this indicates a terminal-to-ground short. To detect terminal-to-terminals shorts, a detector detects when an output of the driver drops below a second threshold. If the detector detects that the output of the driver has dropped below the second threshold, this indicates a terminal-to-terminal short. Shorts may be detected in terminals in one or more write heads. The driver, virtual driver, and detector may be included in a preamplifier. Detecting shorts in this manner avoids the loss of data without impeding performance of the write driver.

摘要： The invention relates to a method of reading magnetic information by means of a read head including a magneto-resistive rod (RMR), which is to be polarized by means of an electrical signal (Imr) and serves to supply a data signal (Vmr) whose variations are representative of the magnetic-field variations to which the read head is exposed. The method in accordance with the invention includes a compression step of the data signal Vmr, which compression step is triggered off when a thermal asperity is detected. The invention enables amplifiers arranged downstream from the device to be protected against peaks in the data signal, without altering the latter under normal operating conditions. Application: hard disk readers.

摘要： Methods are provided for preventing data from being written to a data sector that has been identified as faulty on a disk in a disk drive system. It is first determined whether data of a data sector of a portion of a disk is recoverable. If the data is non-recoverable, an invalid logical ID is written to the logical block address (LBA) corresponding to the data sector thereby identifying the data sector as faulty and preventing data from being written at the data sector. The LBA is then reallocated to point to a different data sector if the data is non-recoverable. Thus, further data directed to the LBA will be written to the different data sector responsive to the reallocated LBA, thereby avoiding writing the new data to the data sector identified as faulty. Internal drive read re-tries can still take place on the faulty data sector even after the LBA has been assigned an invalid logical ID.
摘要翻译：提供了用于防止数据被写入到在盘驱动器系统中被识别为有故障的数据扇区的方法。首先确定磁盘的一部分的数据扇区的数据是否可恢复。如果数据不可恢复，则将无效逻辑ID写入对应于数据扇区的逻辑块地址（LBA），从而将数据扇区识别为故障并防止数据写入数据扇区。然后，如果数据不可恢复，则LBA将被重新分配以指向不同的数据扇区。因此，响应于重新分配的LBA，针对LBA的进一步数据将被写入不同的数据扇区，从而避免将新数据写入被识别为有故障的数据扇区。即使LBA被分配了无效的逻辑ID，内部驱动器读取重试仍然可能发生在故障数据扇区上。

摘要： An application compares TOC data received from a CD player with TOC data in attribute data stored on an attribute list, judges for agreement with each other, and, if agreement is not judged, displays an attribute data table on a monitor. A user judges whether or not a title or the like is to be input, and, if title inputting is judged, inputs associated information such as a title. The application has the input associated information stored on the attribute list so that the associated information is stored in conjunction with identification data of a recording medium.
