摘要： A disk drive system includes a disk controller system having separate head positioning and data transfer subsystems and supporting up to four disk drives, two of which may be removable, portable drive units and two of which may connect through a standard ST506 interface. The removable disk drives incorporate a read and write protected data cylinder for storing information such as the maintenance history of the drive, and a read only cylinder for storing a unique serial number as well as other write protected data. The system also features a high capacity, high speed sector buffer which allows continuous transfers of data to or from noninterleaved sectors and supports concurrent disk and system accesses.

摘要： An optical tape drive including redundant optical heads to continue reading and writing data to an optical tape in the event of failure of one or more optical heads. The optical tape drive includes a plurality of optical heads, each capable of reading data from and writing data to an optical tape, detection logic that detects failure of any of the optical heads and control apparatus. The control apparatus positions each of the optical heads along the width of the optical tape, controls each of the optical heads to either read or write data, receives and moves the optical tape, detects failure of any of the optical heads and performs failure recovery by continuing to read and write data with remaining optical heads. The data throughput rate during failure recovery may be the same as the normal rate for some operations, such as direct read after write. Several different optical head configurations are contemplated. In respective embodiments, the optical tape drive includes two head systems, four head systems, eight head systems, etc., where each head system includes one or more optical head units.

摘要： An optical tape drive that performs direct read after write (DRAW) operations with a plurality of optical heads, each capable of reading data from and writing data to an optical tape. The optical tape drive includes control apparatus that positions each of the optical heads at any position along the width of the optical tape, that controls each of the optical heads to either read or write data, and that receives and moves the optical tape in either one of two directions. The control apparatus performs bidirectional DRAW operations by reversing the direction of the tape and swapping the read/write functions of corresponding head units aligned with a same track. The optical tape drive may include as few as two optical heads, each operable independent of the other, so that the drive may read or write up to two tracks at a time. DRAW operations are performed on multiple tracks by increasing the number of optical head units. For example, four independent head units may be included to perform DRAW on two tracks at a time, eight head units to perform DRAW on four tracks at a time, etc. Furthermore, each head system may include multiple head units organized into an array for aligning with different tracks.
摘要翻译：一种光盘驱动器，其用多个光头进行写入（DRAW）操作之后的直接读取，每个光头能够从光带读取数据并向数据写入数据。光带驱动器包括控制装置，其将每个光头位于沿着光带的宽度的任何位置，其控制每个光头以读或写数据，并且在任一个中接收和移动光带的两个方向。控制装置通过反转磁带的方向并交换与相同轨道对准的对应的头单元的读/写功能来执行双向拉伸操作。光带驱动器可以包括少至两个光学头，每个光学头可独立于另一个可操作，使得驱动器可以一次读取或写入多达两个轨道。通过增加光头单元的数量在多个轨道上执行绘图操作。例如，可以包括四个独立的头部单元，以一次在两个轨道上执行DRAW，八个头单元一次在四个轨道上执行DRAW。此外，每个头系统可以包括组织成阵列的多个头单元与不同的轨道对齐。

The system provides a read and write protected cylinder for removable drives, a read only cylinder for removable drives which may store a unique serial number as well as other write protected data, and a high capacity, high speed sector buffer which allows continuous transfers of data to or from noninterleaved sectors and supports concurrent disk and system accesses.The system provides communication between enhanced disk controllers and enhanced disk drives over a standard ST-506 interface whereby command and status signals greater in number than those normally transmitted over the dedicated lines of the ST-506 interface are communicated between the enhanced disk controller and enhanced disk drive. Standard ST-506 drives ignore, with no effect, the communication protocol of the enhanced communication mode.
